​Actually, reading this more closely, I think you're suggesting that if the
.pac file suggests using a proxy then Alt-Svc should be ignored. Am I
reading that right? If so, that is surprising. Consider a .pac which sends
all requests through the proxy. If two hosts are alternatives for each
other and we already have an h2 connection to one (via the proxy) it would
be great to be able to use that connection​

​for the other host. I hope the spec permits this. If not, I think we
should discuss it more :>
