I think this draft is mostly ready. I just have a couple of comments.

In section 1:
   This revision of the document does not specify the procedures
   necessary to support MVPN customers that are using BIDIR-PIM.  Those
   procedures will be added in a future revision.

Remove this text?

Section 2.1.  MPLS Label

Should one use different labels to distinguish address families in the same VRF?

The PTA must be present in Leaf A-D routes so one can know the BIER
prefix of the router joining. It might be obvious, but I think it is
worth pointing it out. It is specified for IR (in RFC 7988 section
4.1.1 it says: "Leaf A-D route MUST also contain a PTA"...
