This should warn in cases like Homebrew/homebrew-cask#177913, so that authors can add the required caveats.

Looks good! A few optional tweaks.

Clearly I haven't been a mac user long enough, since I didn't mention Rosetta 2 😄.

Did another small addition, and included your changes @MikeMcQuaid

Thanks @SMillerDev

This does not cover the 32-bit intel case from the referenced PR.

❯ brew audit --cask --online nightingale
==> Downloading and extracting artifacts
...
audit for nightingale: failed
 - Artifacts require Rosetta 2 but this is not indicated by the caveats!
nightingale
  * line 5, col 2: Artifacts require Rosetta 2 but this is not indicated by the caveats!
Error: 1 problem in 1 cask detected.

In this case rosetta caveat should not be added and another solution is needed instead as mentioned in the other PR.

Those should be removed:

Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS.

Removed, disabled, or deprecated? pgadmin3 in particular still gets lots of downloads (243 in 30 days).
