Instead of removing this, please add a comment that this is no longer sent as of
Chrome <milestone> due to NPAPI deprecation.

Also, would you mind updating the internal version of this proto in google3 with
the same change?

Will do.
Sure. Can you point me to the location of the internal version?

[piman, 2016/04/05 19:59:28]

Done. I will send you a CL for the internal version.
