If we extrapolate this a bit...
We could propose a "generic blocker" as a strap-on in the queue line. :-)
All that would be needed is for a bot to be weighed in with that blocker at inspection time as an "additional mechanism". Good to go. Hmm... probably need at least N>=2 of them, for each alliance, spares, whatever.
We could even get a little sticker printed up for bots that had been certified "noodle hat capable"!
Kind of like last year's "Nessie" stickers...
