Yes, IMO deprecating the NR bit would mean more uncertainty than
the intersubjective understanding already achieved.
 We should remove any "mandatory requirement" foruse of the NR-bit in IETF std protocols/profiles, however.

Yes, as well as (in a minimalistic edit) change "falsely denying"
to "deny" in 2459. Use of the NR bit should always be an operationalchoice; it is helpful if operational context(s)is/are signaled in the enhancedKeyUsage field.

Yes, agreed also.
 Any PKIX language which implies a dependency betweenuse of the NR bit and any other key usage bit, should beignored for the purpose of compliance testing.

Yes, and I suggest the same should be applied to all other bits
in the keyUsage field.
