Perhaps, but not something we actually need to worry about until we're
contemplating metadata 3.0, especially since whether or not it helps will
depend on why we're breaking backwards compatibility. At the very least,
updated wheel, sdist and installation database specs would be needed to
allow multiple versions of the metadata.

As Daniel pointed out, easy_install and pip also don't follow this rule
yet, so it won't really have any impact if we never get to metadata 3.0.

Cheers,
Nick.
