From a business standpoint, its really not that tbh.
Not giving out dimensions is lazy, I shouldnt have to work around fiddling with dimensions for the only actual part of the custom I can actually change.
Actually if you look back at the reveal party, there were various midsoles and backcages all over the party itself

Demand is unimportant, they already produce the shoes,
you can't tell me slapping laces on is impossible, or changing the base or cage from black or white to a one piece shoe that has to be printed then put together anyway.
I'm all for it being just prints, but graphic prints vs 'the ultimate in shoe custimization' is entirely different.
It's a great start, but not a home run.
I can't really see how chaning one step of the process would be 'asking a lot as a consumer' when it's picking a different puzzle piece basically.
And has it been determined whether the turnback time has been faster or slower then an order of normal fluxes?
