Understandable concern, but XEP-0301 is also an accessibility concern. Deaf people like me, who cannot use the telephone -- should be able to have every opportunity to initiate XEP-0301 if the software supports it. Forcing XEP-0301 supported software to turn off RTT by a spec requirement rather than user preference, is tantamount to putting a call-block on all incoming calls from deaf.... That would be a very discriminatory practice, would you think! Computers, networks, encryption is gradually becoming faster, and even stanza-level encryption for RTT is still is less 'expensive' than a video call, or an in-band file transfer. About your other comments -- good comments!
