They've already asked the WG Chairs to provide lists of preapproved drafts. No info if any chairs did it (none were erroneously sent to the wgchairs list, which could have 2 reasons....)A straw-man to run by the secretariat: if we require that the WG chairs in advance post a list of pre-approved WG -00 document names (requires exact match) to internet-drafts@ietf.org, could they apply the later cutoff date for those documents.
