True, but that's where Thomas's suggestion of attempting to define a
standardised caching convention comes in: right now, there's no middle
ground between "you must use pkg_resources" and "every helper library must
scan for the raw entry-point metadata itself".

If there's a defined common caching mechanism, and support for it is added
to new versions of pkg_resources, then the design constraint becomes "If
you end up using multiple entry-point scanners, you'll want a recent
setuptools/pkg_resource, so you don't waste too much time on repeated
metadata scans".

Cheers,
Nick.
