Yeah and even before they did this, maximise behaved weirdly on a Mac. It didn't maximise to the screen but to the "content" which meant that some apps would not maximise fully.

But macOS (at least since macOS X) has never had a maximise in the way that most other desktop environments have it. To simply make a window occupy the whole screen on top of everything else.
