I use Mate desktop and I know I can do Ctrl-Esc > P > Q for Programming > QtCreator (using the classic simple menu), and I have mapped Windows + R for app launch so can do something similar.
I didn't mean to lump Linuxland into one "we" but I was referring to the general flow of the landscape (particularly in GNOME land) where there was the enthusiasm to simplify (aka "remove features") and do odd UI things to remove the previous 35+ years of desktop interaction for no obvious reason.
Apologies for my generalisation.
Laptops with touch screens started to become standard around that time. Simplifying the UI was targeting these devices. Ubuntu’s Unity was another DE that came out targeting touch.
I’m not saying I liked GNOME 3, or agreed with their decision to make life more difficult for mouse navigation and longtime power users, but it was easier to navigate with a finger. That was the obvious reason why they did it.
