All I am saying is that his so ultra specific hardware works flawless under X11 and that a new solution that plans to replace the old one should support at least the same displays, that should be the MVP - don't be worse then the old cruft.
And I still don't see where the 8 years old article would say anything otherwise, at least nothing that was not replaced by info from the more recent article. And yes, he has linked his old article in the new one but that doesn't mean that every single sentence in it is still fully valid after all those years.
There is a lot of valid points there yes, still don't see where the old article would be relevant for those though, and I think that I really can't say a lot against your arguments in general. All is clear now! Thank you for this longer clarifiation and have a nice day!
