Yeah these look all a bit confusing..

I'm wondering whether do we need the new interface to cover both precopy
and postcopy, or one would suffice?

Both should share the same interface.  I think it means if we covered the
channels interface in precopy, then perhaps we don't need to test anywhere
else, as we got the code paths all covered.

We actually do the same already for all kinds of channels for postcopy,
where we stick with either tcp/unix but don't cover the rest.
