'Making sense' or not is not something that the IETF needs to specify in MUST/SHOULD/MAY terms. There may be reasons to discuss the potential impact of implementing that way, but that is the most the IETF should do. Again, unless there is impact to a 3rd party, putting local use addresses in the global DNS is none of the IETF's business.
