@inthehands @airspeedswift sure, i completely acknowledge that it isn’t a world i’m privy to, hence asking for the context i was missing. i didn’t mean to imply “cases in which finer-grained control is necessary” was a small proportion of cases (though i likely would have underestimated them). that this is an ongoing conversation in the c++ community was i think the key info i was missing. thanks for explaining!
