Indeed, pkg_resources does not support resource access from namespace
packages, only from specific modules or non-namespace packages
contained in a namespace package.  In the face of ambiguity, the
implementation should refuse to guess.  Disallowing namespace-relative
access avoids the possibility of ambiguity, and it's essentially a
non-issue anyway since there's no real use case for "find me whichever
copy of this file got installed first or got listed first on
sys.path".
