dired-font-lock-keywords is nice, but it totally forgot about the more
dangerous SUID and SGID 4xxx and 2xxx mode files! E.g.,
-rwsr-xr-x 1 root root 33 Mar 6 12:59 somefile

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.
http://www.emacswiki.org/emacs/download/dired%2b.el
So 1+ to your suggestion.

Let's hope they adopt them into official emacs.

Unlikely. I've offered Dired+ more than once over the years.
Very few of the features have been added or imitated.

I've now made Emacs 27 font-lock these permissions with the warning face.

I checked the directory /run and there is:
drwxrwsr-x 3 postgres postgres 120 postgresql
where 'w' in group is rightfully highlighted with the 'dired-perm-write' face,
but 's' in the same group is not highlighted with the 'dired-set-id' face.
Is this intentional?

No... Do we need to add combinatorial versions of all the regexps to
dired-font-lock-keywords or is there a better way?

FWIW -
If by that you mean highlight the different privileges
for each possible role (other, group, user), then
`dired+.el' has done that since sometime in the 90s.
(I suggested it for Emacs back then.)
Not a big deal:
(list (concat dired-re-maybe-mark dired-re-inode-size
"[-dl]........\\([lsStT]\\)") ; o misc
'(1 diredp-other-priv))
(list (concat dired-re-maybe-mark dired-re-inode-size
"[-dl].....\\([lsStT]\\)...") ; g misc
'(1 diredp-other-priv))
(list (concat dired-re-maybe-mark dired-re-inode-size
"[-dl]..\\([lsStT]\\)...") ; u misc
'(1 diredp-other-priv))
(list (concat dired-re-maybe-mark dired-re-inode-size
"\\([bcsmpS]\\)") ; (rare)
'(1 diredp-rare-priv keep))

In my test cases, the setguid bit was shown like this:
-rwxrwSrw- 1 larsi larsi 0 Oct 30 13:25 foo-test
But apparently on other systems it's a lower case S?
I've now adjusted the regexp to accept both.

If you have a lower case s then it covers the x.

The upper case S means that the x bit is not set. Try chmod g+x
foo-test and see the upper case S change to a lower case.
