I do prefer this approach as it also fixes issues like "unavailable, but
enabled storage that's not even involved fails migration". And it's also
more intuitive.

But if we really do that, we need to be careful: In particular, we need
to explicitly pick up volumes in the pending section (currently, that
does only happen via the implicit scanning). There might be similar
issues in other situations, but none that I'm aware of.
