That depends on whether this PEP's version scheme is also going to be 
embedded in the code implied by PEP 376.  If so, then nobody will 
have any reason to switch from using pkg_resources to the PEP 376 
pkgutil code, because they won't be able to manage their test, dev, 
and collaboration environments that way.

That's precisely it - there aren't any visible benefits to doing so, 
but there *are* visible problems.

We need to have a way to translate existing version schemes to the 
new one, if we're to be able to have a reasonable upgrade path -- 
considering that these PEPs' only benefit to adopters (at least among 
those using setuptools) is that the code will be in some future 
stdlib version, and support simple uninstalls.
