The change the extension *once*, and make an EAPI spec at the top
of the file for that file format. 

I'd rather have the extension change once, with pain, than with
every EAPI change. My opinion is that reflecting the EAPI in the
file name is a very, very Bad Idea.

No, it means we have to change every ebuild of which we claim
that it works that way. Versioned file structures *without*
changing the extension have been done and they have worked.

Yes, there may be pain along the way. But that is true no matter
which route we go.

What people prefer is in no small way tied to the amount of pain
they expect from a given solution. And they're right to do so.
