PTAL.

Note that this will make "DevTools Companion" unusable; we should notify them
first and turn down the extension from the WebStore.

lgtm.

notifying them today.

okay for breaking canary (more) for now.

lgtm, but double check that's the only place the whitelist occurs. sometimes the
IDs are hashed as well, e.g.
