Recently I saw a use of 'find' to compare dates of 2 files!

Alas, I have no idea how portable find's -maxdepth 0 option is
$ find foo -maxdepth 0 -newer bar -ls
So maybe an old-fashioned prune is the better option?
$ find foo -prune -newer bar -ls

Linux and OSX document maxdepth. However, the section on standards conformance in
a Linux manpage mentions -prune, not -maxdepth. This HP-UX manpage does not document -maxdepth
http://nixdoc.net/man-pages/HP-UX/find.1.html

Is there really a need to add 1000 lines of code to the repository and several new tests and gnulib modules *just for the utilities*, not even the actual program, just to compare dates?

Here's what looks like logic that should work across 40 years of UNIXisms

newer(){ [ -f "$1" ] && ([ ! -e "$2" ] || test -n "`find "$1" -prune -newer "$2"`"); }
