I have never seen anyone with enough menu bar icons to have them hide, nor have I known anyone who ran into that problem. It’s a bug that should be fixed, but I just don’t think it’s as big of a deal as it’s made out to be.
Just because you have never personally seen a bug occur doesn't mean it isn't a problem.
This very article is about how Tailscale frequently gets reports of them being hidden.
And I personally have had the icons hidden. My work laptop has a lot of stuff running on it (much of it is mandatory: VPN, custom company processes, Google Drive, etc) and combined with my personal preferred programs (f.lux, etc) it occasionally hits the limit and goes under the notch.
This is the fairly standard Apple defensework where "it just works, but if it doesn't work it's probably not a real problem" despite plenty of evidence to the contrary.
