interpretation is not at all unreasonable or uncommon because of the poor

I can't agree with you there. I don't recall any clear reference to colorimetric
values being picture referred (do you have a reference in the V2.4 spec. ?),
and in any case I think such an interpretation makes for a poor standard.
The other intents are fair game for manipulating rendering for particular
purposes, but colorimetric should be a sacrosanct, firm base for such
renderings or re-renderings, and therefore needs to be instrument based
(so that they can be verified), as is clearly, and unambiguously stated in V2.4 A.3,
and reinforced in other areas (ie. V2.4, D.3 where measurements are clearly
stated to be flare-less).
