What should we use for the new protocols that we are defining?

Should it be UDP/TLS/SCTP or UDP/DTLS/SCTP?
Should it be UDP/TLS/BFCP or UDP/DTLS/BFCP?

I would like to see some consistency here.

P.S. In the quoted text someone mentioned "UDP/TLS/RTP/SAVPF", should it
be "UDP/DTLS/RTP/SAVPF"?

No, actually UDP/TLS/RTP/SAVPF is what is registered for DTLS-SRTP over UDP with RTP SAVPF profile. See [RFC5764]. The "UDP/DTLS/RTP/SAVPF" is not registered.

So the alternatives for the dependency of default candidate protocol type in your proposal would be:

UDP: "UDP/TLS/RTP/SAVPF"
TCP: "TCP/DTLS/RTP/SAVPF"
