So which do you really want - to know how many directory entries exist,
or to just know if a directory is (non-)empty?  The former would be a
new feature, while the latter already exists as a GNU find extension.

Sorry, but you've reached the wrong list.  GNU coreutils does not
maintain find(1); for that, you'd need to write to the findutils list.
But while you are correct that POSIX does not provide this capability,
GNU find already does what you want:

find -type d -empty
