OK, there are some obvious misunderstandings here... safety.
The reasons that you can't have disc brakes in cross is the same reason you can't in road. Those things get really friggin' hot, and they are already sharp has hell. It's like a little circular light-saber screaming murder me in every crash that could happen. We won't see them on racing bikes until they are safe, which probably will never happen.
Edit: Another thought... You can only get so much braking power on a .5" wide tire. You could put some 13" brembo's and you still are limited by smaller tire area...

The UCI has made no decision regarding DB legality for CX racing therefore DB may not be used. It has nothing lto do with your personal "safety" prejudice. Can you say "overheated rims cause tyres to explode"?
Also, regarding your edit, please actually try DB before you make comments like that.

UCI RULE 1.3.025
1.3.025 Freewheels, multiple gears and brakes are not permitted for use on the track during competition or
training. Disc brakes are forbidden in cyclo-cross training and competition.
(text modified on 1.09.04; 1.01.05).
Or if you would like to look it up.

And yes, it is a safety issue.

meh, the outer chainring has serrated teeth that I've stabbed and cut myself with more than a few times.
the 10sp shimano stuff is extra sharp IMO.

They have made a decision... they made them illegal. The rule is pretty explicit that they are banned. It's not an example of "illegal until proven otherwise so"

I'm surprised this hasn't been answered in 4 pages.
The switch to threadless from threaded was actually to SOLVE a problem that DID exist:
Being able to change/swap out components much more easily:
-With threadless, you can switch the stem (yes, including flipping it) much more easily than you can a threaded... You can switch out the handlebars without removing the brake/shift levers or bar tape.
-Easier to change fork, headset... bearings.
Shall I keep going?
Threaded is still great - it still works just fine... but in terms of ease of use and ability to adjust, a system that is composed of modules - such as a threadless system - is far more advantageous than one with fewer components with fixed-parameters.

1. Adjustable height without tweaking the headset.
2. Swapping stem length is a breeze without taking out the handlebar shifters and brake lever.
