instead of adding a new ContentClient method, which we only do if necessary per
https://www.chromium.org/developers/content-module/content-api, can you use
existing methods on ContentMainDelegate? i.e. BasicStartupComplete?

Yes I can. Other content embedders will need to follow the same logic if they
want this feature, in that case, but it will be easy enough for them to do that.
(And it's not a required feature; unless they want omaha/finch-style updating of
origin trials configuration, it's not needed at all).
