In what scenarios is a GitHub clone URL ever different from what one what “guess”?

I’m genuinely curious — all of the GitHub git clone URLs I’ve encountered were the exact same format. (https://github.com/$user/$repository with an optional “.git” at the end of the URL)

I remember being annoyed that some project which had its name changed - an action that Github gives much warnings about - still had its clone URL as the former name of the project. This was a while ago, I don't remember the details.

Github pages hosted content. But of course that was just a minor digression from the main disappointments WRT their change.
