We said "you won't have to install setuptools" but actually "you don't have to use it" is good enough. If you had 2 pkg-resources implementations running you might wind up scanning sys.path extra times...
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".
