'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.
