We should check that we're not leaving behind an ephemeral, stateless session that is no longer used. I believe we use it for more things but we should make sure.

See inline questions. r=me as long as EWS is happy.

With this change, do we still have guarantees that PCM will not be enabled in ephemeral sessions?

Did we have this configuration before? I'm for it until we are proven otherwise but I want to keep track of any functional changes.

What does this imply?

Yes, that is currently done in a function named pcmStoreDirectory.

Yes, PrivateClickMeasurementNetworkLoader::willSendRedirectedRequest called cancel.

This is what we do for all our sessions in WebKit now.  It makes it so that CFNetwork doesn't look in the keychain for client certificates if the server requests one.
