Currently PMS has what <2.1.5 does.

21:05 < Betelgeuse> zmedico: We should put a note to devmanual that if
you rely on order of things you should use at least that EAPI
21:06 < zmedico> Betelgeuse: EAPI 1
21:06 < zmedico> oh, I mean EAPI 2
21:06 < zmedico> <2.1.5 supported EAPI 1

What is the order that other PMs currently use? If the new order is used
by everyone currently maybe we should change the order for EAPIs like 2
and 3. At least should have the current behavior of Portage for EAPI 4
so that if people need it then they should use EAPI 4. I know that
Portage shouldn't have changed it so no reason to bring it up.
