OK. Lot of shouting since this was sent but not much new text.

How about

    Locally assigned ULA AAAA records MUST NOT appear in the global DNS,
    since there is an extremely small probability that the corresponding
    addresses are not unique. Even though these addresses will be
    unrouteable in the global Internet, their leakage via DNS is highly
    undesirable. Such AAAA records MAY appear in local regions of the DNS
    corresponding to their region of routeability.

(And I would put an equivalent SHOULD NOT on centrally assigned ULAs.)
