I used minisign (and it’s equvalent, openbsd’s signify) as an example of something that could replace one aspect – signing files.
And look, you’ll still have to spend time and familiarize yourself with the pros and cons of anything you end up using. It’s just a suggestion that smaller, single-purpose tools work better for this domain than a big tool like GnuPG.
That said, I’ll keep using GnuPG for now, because it’s literally unavoidable in the way that I need to work with others. Also, because better options don’t exist yet for some things. (git-crypt, there are options, but none better than git-crypt yet, imho).
It’s a general call for people to stop depending on GnuPG for everything…
