Why ng bot is not added here?

[Paweł Hajdan Jr., 2014/10/30 10:19:10]

There is no ng bot for this one yet (and several other ones).

[Sergiy Byelozyorov, 2014/10/30 10:38:24]

Sorry for the confusion. I meant why is linux_chromium_rel_ng and
win_chromium_rel_ng do not replace linux_chromium_rel and win_chromium_rel
respectively?

[Paweł Hajdan Jr., 2014/10/30 10:40:49]

Same reason as other removals in this CL: ng bots are in the top-level
PRESUBMIT, I don't see a need to duplicate that here.

Acknowledged.
