The only fields that make any difference to overhead are in syncpoints
and frame headers. If 3 bits are really sufficient for one of these
fields, then the framecode will do a perfectly nice job without nasty
computational overhead.

Do you mean framecodes? Or flags-style fields? In either case, it's
pragmatic; in the case of flags it's standard practice.

In any case the time for this discussion is long past, by 5+ years..
