what is wrong with that as long existing mechanism work and don't
require any standardization?  is there some ietf religion here?

regarding tcp, outbound should not specify one single mandatory
mechanism for keepalives.  for example, if SIP UA support tcp
keepalives, it should be allowed to use them without sending any
application level data (stun or crlf).
