I wasn't planning on licking any of it, but thanks for the warning.

I commented, agreeing with gibi. Make the exceptional cases

I agree we should steam ahead. I don't really want to hang the fate of
the privsep transition on the removal of cellsv2 and nova-network, so
personally I'm not opposed to privsepping those bits if you're
willing. I also agree that the lack of breakage thus far should give us
more confidence that we're safe to continue applying these changes later
in the cycle. Just MHO.
