I'd be really surprised if the assumptions used by the performance engineers did not translate into printed form for the benefit of the pilot. Normal instrument flight procedures have rules associated with them - and special notes when any of the normal rules can't be applied. And that's before we even think about ATC requirements for flow control and noise abatement.
All of this is spelled out in each procedure whenever some sort of limitation is necessary. I'd have thought that most (if not all) performance engineers would be as aware of the reasons for this as instrument flight procedure designers. Of course, if there's too many notes relating to limitations then it's probably time to re-evaluate the whole procedure...
