It's not a simple and obvious fix either.  It only partially fixes the problem
and introduces other problems.  It's not a good candidate for making an
exception at this stage in the release.

Then please send a fix that fails migration with non-raw images. Not
breaking images silently during migration is critical for 1.0, IMO.

I sent a quick series. If you want to do things different for the blocker layer like add a field to BlockDriver to indicate whether migration is supported and register the blocker in the core code, feel free to do that.
