I can see that, although TBH I almost never have to “admin” EndeavourOS. I just upgrade every once in a while.
Most important to me is being able to find and install whatever software I want, and I have a string preference that it either be installed in my ~, or be managed by the package manager. I really dislike sideloading software globally. And Arch does this better than most. AUR is massive, and packages are trivial to write and install in the rare event something isn’t in AUR.
I agree; it probably didn’t occur to them. But it was a fairly common job in IT in the 90’s. Not a career or job description, maybe, but a duty you got saddled with.
