@vchepkov Well, in fact you can install multiple profiles. I don't know much about use cases, but I've seen some that require, for example, server and client packages, or development and whatever other one, at the same time. How good is that may be debatable, but it's something I commonly see. About being useful, I guess this depends more on who's using the stuff. I understand DNF modules, so their profiles, are there for a reason.
