There's just no way I buy that I could safely make a change in a 100 loc function and know that there won't be an impact 30 lines down, where with a few additional function you can define the shape of interactions and know that if that shape/interface/type is maintained that there won't be unexpected interactions. Its a balance though as indirection can also readily hide and obscure interactions or add unnecessary glue code that also takes up mental bandwidth and requires additional testing to confirm.
