I don't see that as the point, or at least it wasn't mine, but I'd probably disagree in most cases anyway. What is critical for market success isn't for someone to bet their time on unless they stand to directly control the outcome of that market success, kn what would otherwise be labelled agency or a stake in it.
If I'm over here spending my late nights trying to pare down our webpack bundle, but my actual day is already done because it was decided that it should be spent doing something else, then someone is liable to get frustrated with how little influence they have over the outcome or reward system. If a customer then comes back and says "oh I love how snappy it is" you can certainly pat yourself on the back for it, but you have no real control over whether that translates into compensation for your effort, either in terms of accolades or money or product direction, unless you're the one making those decisions already.
Part of the reason, in that specific case, is that not only is it hard to say as an IC what the results would be otherwise had you not done X, but also what future results might be if you were to do X again.
It's not that those choices are irrelevant or that they don't have an impact, but if you don't get to allocate company resources to it, and are hoping for a better outcome but can't control that outcome or perception of your work, then it's not worth it.
If I'm John Carmack, I'm going to care deeply about rendering performance of my game, because if it's great, I might make millions, and I get to decide that that's what my employees are optimizing for. If I'm one of those employees, I'm going to meet his expectations, and if I'm very lucky, he'll think highly of me later on. That's... it. Unless I have decent shares or something.
Likewise if you're repeatedly trying to position yourself as the tryhard, you run the risk of reducing your capacity for doing literally anything else in life, which should be a real concern, because if you're not allocating resources at the company to your time, then you're devaluing your own time and resources for no reason; burnout.
Now out yourself in the same position at a massive company that has hierarchies of managers who's sole job it is to check that the status of tickets have changed or whatever. The chance your extracurricular work will influence a better outcome for you is basically nil, because the value of anyone's job is not defined by anything related to quality.
When you have a certain level of investment of time and effort, you don't have to be John Carmack (owner/founder with your name in the end titles) to care about it. Many people feel pride and ownership of code and parts of products they created, and their investments are responsible for the at least some of the success of the products. These achievements can become defining for their careers, and I think it's appropriate to allow and recognize this.
Management that denies engineers this sense of ownership and achievement is a likely cause of burnout. I think we agree mostly agree, but in my view management shares responsibility in this case.
All of that should be predicated on the answer to the question "How much of the outcome of this work do I truly have influence over?" and if the answer is none, and those extra hours making sure your code is really nice, should only be spent within the constraints you're being paid for. Are your requirements fulfilled, but you were pretty fast and have a bit of extra time to clean things up? Great, that's fine. If you spent your 8 hrs that day, the requirements are complete and there's no more time you're getting paid for, and you don't get to determine what the positive outcome for you is if you donated your weekend to fixing something management doesn't care about and won't pay you for, then don't, and stop having pride in it.
You own it if you own it, keep your personal investment at arms length, lest you become a Jason Bateman character desperately putting in those extra hours so one day hopefully you'll be blessed with that VP position or w/e.
That said, of course if you've achieved something within a fairly tight constraint, ideally you're compensated or recognized somehow for it. Extra worthwhile hours should also be compensated for obviously. But if nobody is willing to pay you for it, it's probably your own undoing.
Seems like we agree in everything except you seem to think that the management's judgement about value is a priori correct and final.
What I am saying is that value in a product can be "discovered" along the way. An engineer that demonstrates how to add value through individual efforts will probably experience burnout if management chooses to ignore their efforts. But more mature managers will figure out how to work with it.
