Can we get rid of the SPDY_PROXY_AUTH_ORIGIN define entirely now (As in remove
it from the build system)?

[Not at Google. Contact bengr, 2014/09/10 21:38:34]

Yes, that is the plan. I have already removed it from chromium/src code. It
Needs to be removed from Android and iOS code as well as all the gyp files.
