This is a known issue. The subvolume itself needs to be set read-only,
and of course that can't be done when the whole filesystem is set read-
only.
But a read-only filesystem should be sufficient, provided it can be
forced to remain read-only thru the entire send. I think that's the
worry, that someone will switch their system from ro to rw in the middle
of a send, thus screwing it up.
But they're aware of the problem and should eventually have a fix. But
I'm not sure how long as there's other work going on too, of course.
