can you uncomment these and link a bug for whitelisting the app for the API
(rather than listing the app name- see
https://cs.chromium.org/chromium/src/chrome/common/extensions/api/_features.m...).

[Luke Sorenson, 2017/05/09 17:41:04]

Uncommented. So you're saying I should create a crbug for whitelisting hotrod
for this private API, and then link that bug in the comments?

[tbarzic, 2017/05/09 21:03:11]

yes (and you can make the bug restrictview-google)- you can see some of the
other links here as an example

[Luke Sorenson, 2017/05/10 17:33:26]

Done.
