I see no harm in adding such a note, and it may help. As for referencing the IMTC best practice document, it is available through a liaison statement at: https://datatracker.ietf.org/documents/LIAISON/liaison-2012-05-31-imtc-the-ietf-imtc-work-on-sip-feature-parity-with-h323-attachment-3.pdf However, I expect this IMTC document to be updated and made available externally once the BFCPBIS work completes, so I am not sure referencing it this way is appropriate.
