maybe we should have another bug for this cleanup, since I think it's going to
probably take a coordinated effort.

[Paweł Hajdan Jr., 2016/03/10 17:56:18]

No, it's just one CL in src, which will be tested on the trybots.

I thought this one doesn't work on swarming?

[Paweł Hajdan Jr., 2016/03/10 17:56:18]

Correct. However, I can't remove it before fixing code in src that relies on it.
And that code can't be fixed until we start providing the new, more
specific/targeted paths which this CL does.
