[oe] Summary of splitting meta-oe discussion

[Philip Balister]

It looks like there was an in depth discussion of splitting meta-oe
(again). Before everyone forgets, can someone put a summary of the
points on her for discussion at OEDAM?

We don't need conclusions or judgements, just make sure your points are
documented.

Bonus points for summaries of the other topics that came up.

Thanks,

Philip
