I think its quite obvious why.
Lets take X-Factor or SCD. In both of these shows, contestants are learning and performing existing material (existing songs and dances respectively).
Same with the Lloyd Webber shows, they are performing "acts" from existing musical theatre.
So in these shows every contestant is taking something that already exists, learning it and performing it to the best of their ability, with 1 week to learn their performance and perfect it.
With this scenario; a lot of contestants struggle; just to learn and perfect something that already exists.
Now put a dance troupe who are performing and original act in that scenario - they have to design, coreograph, perfect and perform 8 different dance routines; with only 1 week to do each. Plus they have to find suitable music for each routine - which is an art in itself.
They would be royaly screwed as it would be impossible to come up with something even half decent in that time and by the time they had done 3 shows they would be creatively exhausted.
Now I am not saying that singing or doing SCD is easy; what I am saying is that placing a dance troupe in an X-Factor / SCD style format would be the equivelant of X-Factor expecting the contestants to write and score their performance on top of learning and perfecting it.
Also; I believe I am correct in my belief that dance troupes tend to have a "product" that evolves over lots of different acts - so there may not be that much scope with past material.
It's not just dance troupes that have this problem either; they are just easier to explain. Groups like Scala would have the same issue as they are "new classical" they would have to do a lot of sound design or rip off Bond throughout the whole competition - which would rid them of all credibility.
Erm... sorry for the bad spelling it's getting kinda late lol
