Hmm that’s interesting, cause on code version 12 and 15 the  “set routing-options resolution rib bgp.l3vpn.0 resolution-ribs inet.0” is the only thing that’s needed, i.e. no need for family mpls on RR interfaces.
So I have a theory that once you enable inet.3 (in any shape or form) then you need "family mpls" on RR interfaces?
