Would be quite reasonable.  I thought since all the existing MATE
ebuilds are EAPI 5 or 6, it'd be wise to support both, but I've only
actually used (and probably will only use) the eclass with EAPI6 ebuilds.

I forgot to include a comment in the ebuild, but the intention was that
the eclass would not inherit python, by design, those wanting to use
that should inherit python themselves.  Although, if I should check that
explicitly, I am unaware of how to do so, and would appreciate advice
from someone, if it is possible. I am aware of INHERITED, but the PMS
says it shouldn't be exported to ebuilds, so I'm unsure if/how it could
be used.

My hope was that since this is used several times (though, not too
many), that I could move this logic into the eclass, but if it would be
more appropriate to just keep that in each of those ebuilds, I can do
that too.

Yeah, I should probably adjust the namespace

Thanks for taking the time to look it over and review.
