Multiattach support has indeed been enabled for RBD as of the Stein release. Though there are the known caveats that you point out.

I thought there was a pending patch to add some details on this to to the RBD driver configuration reference, but I am not finding anything at the moment.

I don't have all the details on that myself, but hopefully one of the RBD driver maintainers can chime in here with better details.

Note that the devstack-plugin-ceph repo also enabled multiattach testing after it was enabled for the rbd volume driver in cinder [1]. So it should be getting tested in the ceph job as well upstream.
