I'm not sure it's used by a large proportion of operators, but it is deployed in some volume in a number of networks that I'm aware of. During the development of implementations, we hosted inter-op testing/fixing at a previous employer. Rolling it out had started when I moved on, but I expect it is now across their global deployments at this point. I haven't heard anything to say that it's causing any issues.
[I still am somewhat unable to reconcile myself with the use of BFD in this deployment, some Ethernet OAM - seemed a reasonable per-member solution to me, but folks have a preference for a single protocol here.] r.
