That's part of what's getting worse: Fracturing/deterioration of the use of distribution package management, instead of improving and expanding it.
> web applications
Another part of what's getting worse: Instead of having compact apps you have to load a behemoth of some web browser/app framework, to do semi-trivial things.
There's also systemd; Gnome having taken application UI in a weird an (IMHO) unfortunate direction, and the fact (?) that the hardware resource requirements have risen significantly.
