We couldn't come up with a reasonable way to preserve support for it.
There was some discussion of this on ovs-dev a few weeks ago (Justin and
Ian Campbell and I were involved).

As I understand it DVS needs to talk to XAPI anyhow, or at least it will
need to talk to it (see bug #2097 and NIC-47), so it seems to me that
DVS could just ask XAPI what name corresponds to a given UUID.  I know
that's more work on the DVS end, but...
