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.
