I think that's fine for the "minimal" approach

Second time I open up this subject, instead of creating a separate profile we should use this option directly:

First of all it installs flatpak related libs which should be up to the user as to which containerization tech he wants to use.

Second of all it also pulls in sddm-kcm which isn't needed if user selected another login manager through archinstall.

This still results in a fully functional system and aligns closer to arch philosophy (plus 1GiB saved in bandwidth)

Doesn't result in a functional system. Tested it in April Arch ISO and it sucks. Can only see a mouse on a black desktop.

Did you test it? It's completely black, only the mouse appears and move.
