It does sound horrific, but mostly because it would be poorly executed by many devs.
Well, and the seeming trend towards install commands that look like curl $file.sh | sh
But if they’re not actively encouraging that, I see no issue with a well maintained install tool, created from well maintained toolsets that work on essentially any platform.
Underrepresented at best, at worst it’s arguably too easy to forget that Alpine is more than just container images.
Not sure how to solve that problem, it’s my go to for rolling an image but wouldn’t normally make the shortlist for standalone machines. In a prod env, that’s basically Deb, RHEL derivatives, etc. In a personal env for me, Arch derivs tend to win out on non-critical services if only because I invariably learn something useful that I wouldn’t want to learn in prod.
