As long as nobody minds that wheel uses Provides-Extra, utf-8 and
description-in-body right now. I don't think those particular features are
controversial.

The current distribute (pkg_resources) implementation only parses
requirements out of metadata if it is inside a .dist-info directory and
only uses requires.txt if looking inside .egg-info (and does not have to
open or parse PKG-INFO at all in this case). So if you are using .dist-info
(used by wheel) then you need Metadata 1.2+ and if you are representing a
very significant portion of setuptools projects you will need
Provides-Extra.
