p2 5.1.1 "Requirements for HTP/1.1 proxies" bullet one effectively requires proxies to forward ALL requests with Expect: 100-continue if the inbound server is HTTP/1.1 -- even if the request is a GET.

I know that this isn't the intent, but that's how it reads; suggest qualifying this to only apply to requests with bodies.

The next bullet requires proxies to respond with a 417 if the inbound server is HTTP/1.0. Just curious here - why? Wouldn't the maximally interoperable thing be to generate a 100-continue yourself? While the client *could* resubmit the request, they probably won't, because as far as they know, the origin told them not to.

Cheers,
