Implementation usefulness. Why bother adding code that barely gets used (and that is unlikely to improve in the near future), adds complexity, code bloat, etc...? SCTP/UDP has a much higher likelihood of usefulness. But as Roberto has mentioned, it still has deficiencies, mostly around RTTs (connection + DTLS setup). If they can be fixed, great. Let's do it.
