Makes sense to me! Some tests might be nice. Is this a companion to #16595? Do either of those PRs require the other?

Yes, but they don't require each other. This one follows the refactored logic from #16595 though.

@reitermarkus I'm getting lots of such errors.

Also during the brew upgrade:

➜  ~ brew upgrade
...

==> Upgrading htop
  3.2.2 -> 3.3.0 

==> Pouring htop--3.3.0.monterey.bottle.tar.gz
==> Caveats
htop requires root privileges to correctly display all running processes,
so you will need to run `sudo htop`.
You should be certain that you trust any software you grant root privileges.
==> Summary

Seeing the same issues as @aivus. Reverting to the commit prior to this merge (cd9c3fc) allows formulae and casks to install again.
