I think the situation is as follows (likely obvious but it may help to
make sure we are all on the same page):

- the NI and LNE models have a normative reference to
  I-D.ietf-netmod-schema-mount (and this makes sense since there are
  MUST sentences in the I-D)

- I-D.ietf-netmod-schema-mount (last updated in October) has normative
  references to RFC 7895 (old YANG library)

- RFC 7895 does not work with NMDA, NMDA work on a YANG library update
  replacing RFC 7895

So the YANG library update is gating the schema mount update which is
gating the publication of the NI and LNE models.

A proper solution would be to prioritize work on the YANG library
update and the schema mount update. I assume that the next revision of
the YANG library update (say end of January) is ready for WG last call
and perhaps the schema mount authors can take an effort to get that
document there as well, say beginning of February.
