It is not very complicated. It looks like the characters are mostly 'python identifier' rules with a little bit of 'package name' rules.
I am also concerned about the amount of parsing on startup. A hard problem for certain, since no one likes outdated cache problems either. It is also unpleasant to have too much code with a runtime dependency on 'packaging'.
Wasn't someone working on implementing pkg_resources in the standard library at some point?
The idea has been raised, but we've been hesitant for the same reason we're inclined to take distutils out: packaging APIs need to be free to evolve in line with packaging interoperability standards, rather than with the Python language definition.
Barry Warsaw & Brett Cannon recently mentioned something to me about working on a potential runtime alternative to pkg_resources that could be installed without also installing setuptools, but I don't know any of the specifics (and I'm not sure either of them follows distutils-sig).
