Quoting CiaranM from a different subthread, defining EAPI:

Now, we already had someone mention using two together, prefix (which 
seems to have been defined as an EAPI for the purposes of this 
discussion, I don't deal with it so haven't the foggiest about it, 
personally) and EAPI-1.  If that portion of Ciaran's definition quoted 
above stands, that usage would be defined as illegal, thus anything using 
it "broken".

The work-around as Jim mentions above would be defining a third EAPI 
combining as a superset the other two.  One could then create ebuilds 
using that third EAPI.  Of course, until at least one of the available 
package managers supports that third EAPI, ebuilds created to use it 
wouldn't be of much use, and until portage, being the official Gentoo PM, 
supported it, said ebuilds could not be placed in the Gentoo-x86 tree.

The question, then, is whether anyone, particularly those working with 
PMs other than paludis (Ciaran being the lead on it so presumably his 
EAPI definition works for it), disagrees with that portion of Ciaran's 
EAPI definition.  I've seen no such direct disagreement so far, with the 
presumed exception of the person mentioning already combining two 
(without creating a third out of them) in prefix, of course.
