You probably mean "packager". The developer isn't necessarily
the same person, e.g. a user might want to build from source
then redistribute a package in some other way.

Please don't change defaults: this only introduces hassles for
packagers since they'll have to add multi-version support to
their setup.py which only complicates the process.

If you want to add new functionality, provide a command option
and then use that in your code. If you want to use this as default,
place the option into the setup.cfg file.
