OK.  So, I am not sure what to do here.  I will say several things ...

(1) I believe that as a general, default the document is quite right
    in specifying a congestion response and exponential backoff.

(2) I believe consensus of the WGs has been the same as my notion in
    (1) for some time now.  So, even setting aside (1), I am not
    sure I feel like I have carte blanche to change this.

(3) I do not believe loss always means congestion and I do not
    believe assuming such is always correct or should always be
    done.  I don't think I know anyone who thinks that.  So, the
    document explicitly says that is fine, just go get consensus
    that some other approach is fine.  (And, that should be
    happening regardless of this document, so I am not sure what the
    big deal is here.)

So, basically, I am not sure what to do here.  Maybe one of the ADs
can help.  Or, maybe we can set this aside and I can do the things I
told you I'd do and a little extra framing will make this better.  I
am all ears for advice here.

(BTW, I have a half response to Stewart, as well.  I am not ignoring
his review.  I am just behind.)
