You are so right with regression and slow sofware. Tryd to install rhel8.6 on a t61p from 2009. Gnome alone used half the vram around 130mb. And was slow as hell. Git is fast? Ever tryd to use it with 3gb of ram and a laptop hardisk? Switching branch on a linux repo took 4 minutes. I then converted the repo to a bitkeeper one (took about a week), changed to freebsd and the laptop was usable again...with i3 the nvidia drivers and bitkeeper. I really think dev's should test resonable sofware on a 2g raspberry or something like that regularly.
