The part that got me is a single fork turning into billions of valid URLs, because every commit, diff and plain render is its own page. I run a small Gitea behind Nginx Proxy Manager, and a forge is exactly the kind of app where that math applies even at hobby scale. This has me checking whether anonymous visitors need the commit and diff views at all, or whether putting the web UI behind a login would cost me anything. Clones over git would still work for anyone who actually wants the code.
