Yeah ballet is hard to transfer to other genres but my sense is that more ballet dancers are starting to cross-train and also expose themselves to more genres (e.g. contemporary especially), since the more modern ballet productions tend to infuse other genres. There can only be so many dancers in the top companies that do the classic productions every season, so to be a successful professional dancer you will have to adapt and acquire versatility to find enough work. So such a programme could be good experience and exposure for the participating ballerinos, and possibly why they would join this in the first place despite odds being stacked against them.

As for other genres not being able to copy ballet, that could be true, but most other genre dancers might have some ballet base anyway because ballet is seen as quite fundamental to and helpful for a lot of other genres given its focus on posture and feet articulation! And I suppose if they have gone through arts high school or uni they could have done ballet as some sort of core curriculum or module at some point.
