For me, I would say that unless the implementor in question has experience in
designing protocols, and fairly deep understanding of that particular area, they
are not in a position to make a good judgement on whether or not they can ignore
a 'SHOULD'.
FWIW, IMO "SHOULD" should only be used in docs when accompanied by a
description of a known or suspected exception case.
Otherwise it's just a wiggle-word variant of MUST, and there's no point
in being vague in a spec.
