This might interest knreed, or knreed might even have been the initiator of this for the FAH2 Async application, which needs fast turn around. The github entry reads as if will be able to set the instruction at app level if a result has to be reported immediately, like presently all do already across the board on the Androids, but that's a client side default cc_config setting.

For sure, this becomes an additional available tag for app_config for whenever there will be a next build... maybe the Dr (A.) is gearing up for a well overdue one... might even be a 7.7 alpha which leads up to 7.8 beta.

(looks like I wrote the same thing 3 times ;P)
