I’m not sure we require marking for all those; indeed, I think we should probably require that to get *in* to the Evergreen spec., you have the specs and implementations already.

Marking age on every feature is impractical. In case of doubt, pull a 180-day-old version and see if the feature was there then. It’s cooked if (a) it was and (b) there are no pending objections, errata (which DO require marking).
