Thank you.

I think I found a reasonable way to preserve compatibility here, so I
emailed out a 3-patch series that I believe does so.  The first patch is
just the same as what you sent, the second patch fixes up compatibility,
and the third deletes the now-unused dump-vif-details.

I've been trying to test it, but various problems keep getting in the
way, so I'll have to do that later.
