note that the server version already has used this tag for a different purpose,
can you make sure we don't collide?

[David Roche, 2013/04/04 01:39:53]

Done.  Will field #7 be added to the client proto?  If not, and it is
server-only, it should start at 100 to make keeping these in sync easier....

[Mattias Nissler (ping if slow), 2013/04/04 13:18:34]

Field 7 will appear on the Chromium side as well, in fact there's a pending CL
that adds it.
