Please file issues on the pypi-metadata-formats repo, that's one of the things it is for. I already created one requesting a flag to indicate whether or not a package supports meta-imports: https://bitbucket.org/pypa/pypi-metadata-formats/issue/17/add-wheel-metadata-to-tag-meta-import (along with one for the linux distro tagging and a more controversial one to support more flexibility in the final installation layout) Cheers, Nick. > > On Jan 30, 2014, at 10:56 AM, Daniel Holth <dho...@gmail.com> wrote: > > > I see you've noticed wheel was released in an imperfect state. > > > > Let's add a Zip-Safe flag to the WHEEL file, values of "true" and > > "false" same as Root-Is-Purelib. > > > > Daniel > > > > On Thu, Jan 30, 2014 at 10:44 AM, Eric V.
