Right, this is my perspective as well. The point that the wheel format
already includes a build ordering field was significant because that file
naming scheme has an official specification.

Other commands like bdist_egg, bdist_dumb and bdist_wininst aren't as
strict about the expected file names, although it would be good to define a
suggested optional build numbering convention at least for bdist_egg, such
that easy_install will do the right thing, even if the full source level
version number isn't bumped.

Cheers,
Nick.
