macOS is not usuable without a proper tiling window manager. You double click on a window and it enlarges, but doesn't take all of the screen. Seriously, wtf?
You fail to understand the difference between ‘usable’ and ‘works according to my exotic preferences’.
If you ‘need’ a tiling window manager, MacOS is not for you, Apple is never going to add one and is only going to cripple attempts by third parties to do so.
You fail to understand the difference between owning an OS and merely using it the way Apple intended. macOS is notorious for poor handling of windows, I don't need to explain that.
No, MacOS is an opinionated OS, well known for the droves of armchair UI designers smugly criticizing it while they keep buying the hardware. It has been that way since forever.
