Sorry, would "functionally inferior" be a more suitable name for it? I've come to expect robust and fully-featured WMs from years of using Windows and Linux, it's a bit funny to me that Apple has just given up in this respect.

Broken might be a bit heavy-handed, but it's not like I'm chiding some tiny mom-and-pop store for writing bad software. This is Apple, a company that has been developing their current operating system for nearly a decade. In that time, the closest their window manager got to a glow-up was the introduction of split-screen tiling. Pretty pathetic if you ask me, which is why I have to install Yabai on every godforsaken Mac I own. I'm not following them into the ARM transition if they don't fix the basics of their OS.
