If I remember correctly the use of "prow_ref" tag is normally when the reference is taken from the Council ROW information documents that are compatible with OSM. 'ref' is used when the Reference itself is on the signed on the ground. Thus for the Isle Of Wight, it is probably recommended to use the 'ref' field since I believe most if not all ROW on the IOW have the reference on the sign posts. Whereas for most of the rest of England and Wales, only rarely are the ROW references put on sign posts (I don't know of anywhere else that does it consistently compared to the IOW). The only times I normally see ROW references are on permissive notices or temporary route diversion notices. Thus similar to the recommendation for 'C' road references vs A/B Roads. Visibly signed things go into 'ref' so used for A/B roads. 'official_ref' or similar should be used for C roads.
I'm unsure why you feel there should be a difference in tagging when it's signed on the ground. They refer to the same objects as would be listed in the Isle of White Council ROW information documents, so should be tagged prow_ref.
FYI The agreed tag for 'C' roads was highway_authority_ref as it was felt there could be other official or authority tags. It's always good to be specific.
