Should this have more specific name like 'for_origin_trial_feature'. With
runtime-enabled features, this seems ambiguous.

[iclelland, 2016/06/10 20:24:01]

The intention was to eventually also include runtime features as well, and split
them off so that RTE features could be initialized one-at-a-time.

However, that's for another day, and I can change the function name at that
point, or do something different, maybe.

Changed.
