I still maintain something like that can't be an optional feature, and they'll have to go all in or remove it completely. Programming and maintaining the functionality in 3rd party apps for a small subset of macs, and then creating a version without that functionality for the rest will mean software developers never going the extra mile to come up with the features that will make it what apple want it to be.
I just got my computer and after realizing how little I liked it I started searching around. People REALLY hate it. I seem to remember Apple completely reversing course once or twice after they realized they had a flop. Heck they called Apple TV a "Hobby" the year after it was released.
