Using apt, yum, pacman or the equivalent is still just a single command. Your implication that "manual installation" is extra work when it is a single command on all the desktop distros.
Saying that "executing a single command" is too much manual work is simply delusional.

Nonsense. I'm currently running Plasma, which was not the default. I've installed so many in the past on this machine that I lost track of them.
I've switched DEs and window managers multiples on this machine, with no problems.
