And then everybody else pays with cycles for the detection of the
special use case. Oh, yeah.

I only today run (again) across QDataStream performance. Super
convenient, super flexible class. And easily beatable by a factor
of ten in performance for each and every individual use case.

So - no, you should not have to explain *each* use of a map to your
manager but for central parts of performance critical sections you
should think twice.
