Your other issues were also addressed, the non-universal configurations by pointing out most people work in one or two environments most of the time. Worst case, it’s hard to imagine a quick disabling of conflicting macros being too large a price to work quickly in an environment for weeks or years.
I do concede this doesn’t solve any problems of yours as you don’t value what you do with your keyboard very much.
Lol. I want to type full words, and feel that doing so is near frictionless. I access around 70 environments regularly, many of which are frequently re-imaged during testing, and I appreciate the fact that typing works the same on all of them. My co-workers also appreciate that I am not installing weird typing macros on our devices.
Efficiency for me is not the same as efficiency for you. Deal with it.
I'll also add that something like vim is specialized and very useful. It is easier to use vim in a mouseless environment, which is sometimes a necessity. I use it fairly well, and it has paid dividends on the time invested. I can appreciate the value of a good tool.
But typing speed is not the same as efficiency because standards are efficient in their own way. I'm sure you'll say "oh, you don't value words and have nothing important to say", but that's a ridiculous argument. It is simply that, in my opinion, this type of thing is not worth the overhead it creates, much like extremely customized vim configs. Time is invested in the pursuit of efficiency, and it is never returned. One day the config ceases to function correctly, or your friend/coworker/family member tries to use the keyboard and can't use it effectively, so it gets disabled.
