There are many other reasons why SIP messages are getting bigger and
bigger, of which STIR/SHAKEN is not the first, second or fifth: other
standards, WebRTC interop, more/wideband codecs in SDP bodies,
SRTP(-SDES/DTLS), support for other features and standards, etc. So,
this problem needs to be dealt with one way or another and is pervasive
irrespectively of STIR/SHAKEN.

The solution, of course, is to use SIP over TCP.
