Barry: to the extent that your shepherd's review was to take into
account my last call comments which went unanswered, this was
part of my last call comments and obviously haven't been accounted
for. Removing useless countermeasures from this document was part
of what I asked for and I still ask for.

I remain very disturbed by the prickliness of adding text that point
out the shortcomings of oauth in embedded/app environments or
removing supposed mitigations that are not plausible.  This is a
threat document, not a sales booster pamphlet.
