Whatever worked is highly unlikely to stop working.
New to software development, are we? That is such a laughably bad assumption that I’ll assume what I think you meant to say is not really what you meant to say.
But I’m glad to know that editing slides works just fine in Excel. From the link, “Gold” means: “Works as well as (or better than) on Windows with workarounds.” The test results say online login crashes. That tells me their certification program doesn’t mean shit.
It's not a certification program. It's just reporting system.
And yes, it is what I meant. For software like wine, if something works in version X, you can expect it will work in X+1. Sure, there will always be some regression from time to time, but wine's whole existence is based on the idea that they support Window's APIs. These are not random features they'll decide to remove from time to time.

Anyone that expects this is setting themselves up for disappointment.
My actual experience with this has not matched yours. Wine is extremely fragile. There is a reason why things like winetricks and using dedicated wine prefixes exists, for one.
This is not a knock on wine really, but the complexity of the problem at hand.
> These are not random features they'll decide to remove from time to time.
Emulating windows APIs is extremely complicated. Even with the best intentions of not breaking something it happens, quite a bit.
Whatever worked is highly unlikely to stop working. You can expect better support than in past test.
