I know a lot of arch users that do that, especially if they just use simple window managers like i3 or window maker. Though, on a wayland system startx doesn't work, each compositor has its own command
Huh. If you go through the hazing of installing arch without that new installation script, it is consistent, I suppose. One thing in favor of this approach, is that it is very straightforward.
Not what I'd choose, but I think that is the beauty of the whole free software movement - one thing you get in utter abundance is choice.
