Alternatively we can keep dtls-id the way it is currently defined and
define tls-id to be used for TLS-over-TCP  in the new draft.

I would also prefer a more generic name for the TLS extension itself. It
does not have to be related to SDP, so some sort of endpoint_id would work
better then sdp_dtls_id.
