I agree with this wholeheartedly! Even something a small as fixing up some horrific diverged orphaned git history can help me on a hobby project. And the fact that I see the commands that, or the way a containerfile/caddyfile is written, helps me learn along the way. Not as good as a textbook, but like the author I'm reading a textbook for <this thing over here> not <that boring infra stuff>.
