Err, that's jut because we haven't gotten to it. The whole point of the
ops is that we do want device removal (and in the future resize)
notification for others users as well. In fact what drove me is to
have proper notifications for a removed devices in md parity raid, I've
just not gotten to that quite yet as I've been busy with other things.

Vut even if that wasn't the case, calling straight from block layer code
into file systems is just wrong.
