The glep is quite clear on that point.

It's not all that invasive. All that changes is that the EAPI goes at
the end of the filename and you don't set it in the ebuild. Developers
should be able to keep up with this, and if a user asks it's easy enough
to say that "it's a new version of ebuild, it has newer features see
www.blah.org/blah for details". And really, users already ask what EAPI
is so it's not that much headache.
