So going forward, we should put all spdy/quic/whatever flags here?

[Bence, 2016/04/22 11:11:28]

Yes, that is the plan.  Since NetworkSessionConfigurator is a component and it
needs access to these flags, and components cannot depend on chrome or content,
new flags should be added here, with the understanding that when called from
iOS, command line is not parsed. (However, I have indeed seen that iOS
developers have decided to fork three of these flags as
kIOSIgnoreCertificateErrors, kIOSTestingFixedHttpPort, and
kIOSTestingFixedHttpsPort, but the rest are ignored.  Maybe there is room for a
follow-up CL.)
