well, if you want to focus on the $now, then you're mostly correct.
however, as we've done in the past, it's generally pretty easy to
implement functionality in say eutils.eclass so that other places
don't have to worry about different EAPI code paths.  then in the
$future, there is only the code provided by EAPI.
