we are talking about the other way around I think: package with the
subslot is already eapi 5, package wanting the := dep is converted in
place

in that case, installed package will not have the := dep in vdb, thus
will not be rebuilt; when updating libpng, old school methods will still
work, and once that is done the := dep will do its job in the future.

I agree it'd be nice to have everything rebuilt automatically when
going from libpng 1.5 to 1.6 but I'm seeing it the other way: I don't
understand why I need to rebuild half of my system just to be able to
automatically rebuild it again later.
