I have yet to see it officially done at a test. A lot have been "grandfathered" with Seisan bunkai. I do not mind the addition. Certainly, some can quibble (Bill!) about the applications. Why not make prospective seniors devise their own?
Just a thought.
When I tested for nidan in a Shotokan variant, part of our test was to devise our own bunkai. personally, for whatever it is worth, (which may be very little, I'll admit), pre-determined bunkai are very good teaching techniques for learning how to interpret kata, but by dan level, (and I'm being politic, here, since I actually think that people should be making up their own bunkai by the time they reach green belt), I think if you're tied to the "official" bunkai, you're robbing yourself of the value of your training.
I know GEM has talked about the reason for the official bunkai as giving the testing boards some standardization for the purposes of testing, but, and I mean this with no disrespect--that's bureaucracy, not karate. So, with that in mind, who really cares what different people do as their "official" bunkai? What difference does it make outside of a test?
