Yes. It was simply a standard Zimbra MMR deployment.
So out of curiousity, I deployed this configuration again (2 MMR nodes with
delta-syncrepl, 1 consumer) and it no longer manifests. So it appears one
of the many fixes to replication in the nearly 3 years since I filed the
bug resolved the issue. I've closed the ITS.
So generally, I'd say then that it should be OK to deploy in that way.
