I agree, Gnome can CSDeez nuts. They're really ruining my tiling window manager experience. Worse still than the death of global menus is the death of unity HUD style interfaces which were just catching on (press alt button to start a search interface for all the menu options) they were so nice for the likes of gimp and open office.
Sorry if it's moderately less "ooh ahh shiny" but it's objectively an incredibly efficient way to find things. Gnome has posed no valid alternative for this and several other features that they have sunset.
As a sway user even I agree with this move. We don't need our own apple-like entity directing the course of Linux UI design toward pretty walled gardens. We can have our pretty and approachable UI cake and power user/traditional desktop features too!
