My idea was that maybe centers are made after edges(i wouldn't think that).
Then it would make sense to only scramble centers so you could practise them. If the edges are messed up after finishing centers, you would know you made a mistake. If the edges were scrambled, you wouldn't be able to tell.
This is why I wanted it - if centres are messed up but edges solved, the mistake was probably in memo or breaking into cycles, if edges are scrambled, the mistake was in execution. If there isn't one I'll probably stick with scrambling normally then solving a cage.
