I've offered all of its code to Emacs many times.
And in the past I've suggested certain parts in
particular, and sometimes submitted patches.

The only such change I recall being accepted was
to highlight `w' for writable permission in group
and other columns.  And the face for that by
default is `default', which means that to get the
highlighting you have to know that face exists
and customize it.
