Now that I have arch working for my needs, I spend hardly any time maintaining it.

The only issues come up when some sort of breaking change is released, and in that case there is always an article right on the arch homepage for steps to migrate to the new package.

and I suppose if your needs are limited cause you only need common services (emacs, firefox, tmux) those incidents will be pretty unusual?

Very unusual. The one time I had a fair amount of issues to resolve was when Arch switched to python 3 as the default, instead of 2. Fortunately, this is not something they do lightly or frequently.
