FWIW -

Dired fontification of permissions came from my suggestion many moon ago.
Acceptance was half-hearted and the feature was implemented only partially.

The different permissions have been highlighted individually in Dired+ for
decades, including the ones you mention.

So 1+ to your suggestion.
