If you check back to April 2009 in this thread you'll see that my very first yakuman was a counted one (I had more dora than you too!) but I haven't made a kazoe yakuman again since then.
In terms of rarity, even sanbaiman hands (11-12 han) occur less frequently than some of the named yakuman hands.
I've also chanced upon this vid of a snippet of some old looking japanese movie involving a young punk going up against this older guy (i'm assuming like a yakuza boss). In the vid the young punk had called for 4 kans in the one turn and was waiting for a pair at the end. The person going after him called a 5th kan, thus ending the round.
It's not a situation you're going to see every day, but you need to have a rule just in case! The online English documentation for Four Winds Mahjong says that the declaration of a fifth kong in Japanese mahjong when someone is going for Sū Kantsu will force a drawn hand. The fifth kong must always either immediately end the hand or be disallowed of course as there would be no more supplement tiles and kan dora indicators in the dead wall.
Do you have a link to the clip BTW?

Looking in one Japanese book the abortive draws are listed as "local rules" (therefore optional, although the same applies to other common features like Ippatsu and kan/ura dora). A summary of a specific rule-set in the back of another gives them as nashi (disallowed). They're just one of those things (those many things) which you need to agree before play.
(I would hate to deny you your monster hand, although my opinion might differ if I was one of your opponents when you made it!)
