It is only there because distutils has a purelib/platlib distinction, so the spec represents it. See http://hg.python.org/cpython/file/49de26395d1a/Lib/distutils/command/install.py#l85 Ok, so does this mean Debian would have to build their own installer if they want to spread the wheel's contents as appropriate for their directory layout?

Sorry if this is a lame observation, but Debian has already built their own installer called dpkg.

The Python-specific binary format will mainly be used to populate virtualenvs. It may also turn out to be a convenient intermediate step to build an .rpm or .deb but that is not the primary design goal.
