I'm sorry to say that the need for this protocol extension, and its
proper semantics, have yet to be established.

I don't think it was appropriate to repost the patch in this form
while the conversation on those topics is ongoing.  It would have been
appropriate if the patch contained answers, or at least forward
movement, in that conversation.  But regret to say that this version
of this patch does not do that.

This seems to be a response to my complaint

  I would like the base64 encoding to specified much more explicitly.
  Just `base64 formatted' is too vague.

By that I meant that the specific exact base64 format (of which there
are of course several dialects each with various variants) has to be
specified, probably by an reference to a suitable external
specification.

I did not mean that a general dictionary definition of base64 should
be cut-and-pasted from Wikipedia into this specification document.

Thanks,
Ian.
