Oh, interesting. Is this behavior we're expecting to make use of?

[Bence, 2015/09/14 21:56:16]

I really do not know.  There is nothing QUIC-specific about alternative
services, they could be used with other protocols like HTTP/2 as well.  But if
you want, I can gate |use_alternative_services| on |enable_quic|.  I do not have
a preference.
