This feels slightly malicious, but I can’t help but admire the curiosity that takes someone to actually see what happens if. That said, now we know, so nobody else needs to bother GitHub engineers by doing this again, hopefully.
So even if people were to try, I don't see that being a big bother. Not that it's not malicious to do this now
Monorepo's in particular could be impacted
(Understanding we’re waaaay off in edge case territory here and this is all basically academic.)
