Of all the Linux features to copy, they chose this.
*GNOME features, not Linux features. No such issues over here on KDE.
I have often felt like GNOME is the most Apple-y of desktop environments; they're very form over function. Not surprising to me at all that both would pick a design that seems beautiful until you try to use it.
KDE doesn't actually suffer from this problem.
Shortly after Windows 10 came out I was joking that Microsoft finally made a Linux distribution (by replicating all the jankiness we usually associate with it).
Now I guess it's Apple's turn.
I actually wish macOS would clone Alt-dragging from anywhere to drag and Alt-right clicking to resize from anywhere from Linux (at least GNOME and KDE Plasma have this built-in). That would certainly solve most of the complaints in the original post.
