I only implemented support via extras, and the feature wasn't officially
supported (still isn't, I don't think) because the PEP specifying the
syntax wasn't fully baked yet.  I figured that if *only* setuptools itself
used it, then if the syntax changed only setuptools would break...  but fix
itself at the same time.

The same cannot be said for any other package, so use at your own risk.  Or
better yet, don't use it.  ;-)

(At least, not until it's a documented feature w/a PEP-approved syntax.)
