John,
the best solution is a short note on relevant pages (perhaps even in the footer of every page) that says, e.g., "In accordance with International Standards, all dates on IETF web pages are either spelled out in full or in ISO 8601 format, i.e., YYYY-MM-DD". It is not trying to swap out one ambiguous format for another one that might be slightly less (or slightly more) ambiguous.
