Looking at hammer release, it seem that currently it can be only defined on rbd volume creation.

But a new patch in ceph master allow to change it on the fly.
I have sent a mail to the ceph mailing to see if it'll be backported to hammer soon.

Oh, I did not thought about that. So I think we should not enable it by default.
