I lean in the direction of making PADDING not count (and not require an ACK), because i'd like both sides to be able to pad packets that would otherwise be ACK-only without inducing a feedback loop.

That would distinguish PADDING from PING as well.

Another alternative (voiced by @ekr at the interim, possibly facetiously) was to allow/encourage the use of ACK frames as padding in general.

Or, we could allow ACK frames to be arbitrarily large, which would let us use them both as ACK and as PADDING -- that would also let us get rid of PADDING.
