Well I’ll back up the grandparent comment: I don’t want it to look crap, but it being entirely native Cocoa doesn’t bother me either way. It’s nice when an app is, but as long as it’s not horrible to look at or use, I’m happy. I know a lot of my fellow developers where I work are the same way, so I don’t know how true your thesis is on the majority wanting “give me Cocoa or give me death” — but I’m arguing anecdotes with anecdotes haha
I’m very surprised at that, since myself and most of my friends value very much of how the UI is Cocoa.
I’m pretty sure a majority of the macOS user base considers the macOS look-and-feel very importantly.
