I don't think we should make it public on dev just yet. We still don't have a
clear plan on how we're going to deal with arbitrary apps providing search
results and listening to queries (security/privacy implications as well as
search quality implications).

Happy to enable this on stable/beta channel for File Manager, but we are in no
way ready to open this up yet, even on dev.

Okay, we will go with whilte-listed for now.

Do you also need "channel": "beta"? Or does stable automatically imply beta and
dev? (In which case, you should remove "channel": "dev" entirely.)

[benwells, 2015/05/12 02:51:19]

Stable implies beta. This is correct, assuming public on dev and whitelisted on
stable is what's desired. But I agree with Matt, this should stay whitelisted
everywhere until we have ideas on how we'd make it public.

[yawano, 2015/05/12 03:27:44]

I simply removed dev.
