and distlib seems to be implementing them.

and "exports" seem to be entry points 2.0.

so theoretically, when PEP426/PEP459 becomes live....

what does that mean for setuptools-based projects? (I understand that we might not have a clear idea now, but just trying to narrow down the possibilities)

1)  the setuptools "entry_points" keyword (and pkg_resources api) gets re-implemented to understand PEP459 exports?

or

2) "entry_points" keeps the old implementation, and possibly tools are written to handle the old and new metadata?

or 

3) "entry_points" are stranded, and consumers have to rewrite setup.py files to use some new keyword that understands PEP459

or 

4) something altogether different...

as for why I'm asking, pip itself is considering command extensions, so it's a direct practical matter for us.
