Functions should not contain too many return statements

In task T256942, there is a request to deactivate the "Functions should not contain too many return statements" rule. I've deactivated it (for PHP analysis) while we discuss whether it's useful to re-enable.

Personally, I sometimes find it helpful as a reminder that a method is doing too many things; other times I ignore it as it doesn't make sense. I don't have an opinion on whether we should keep it enabled or disabled for the MediaWiki PHP profile.

Its a personal coding style choice and often more returns can make something more readable, not less; eg for any possible error that is found, return early, rather than wrapping the rest of the code in a giant `if` block to ensure there isn't an error found. Fully support deactivating the inline comments from the bot, though if it wants to take the returns into account and note them in its general comment for the patch set that would be not as annoying imo

Yes, that's an option. When we were on Gerrit 2.15, I started prototyping that because robot comments were barely supported in Gerrit 2.15. Because you can't use HTML in your comments, you'd end up with the current general soanrqube bot comment followed by something like:

I guess this isn't so bad; the overall goal is for a human to at least scan the comment to see if it's something worth addressing which the previous implementation didn't do (I imagine a lot of people just ignored the "SonarQube build failed" message). Do others have feedback on this?
