That is peanuts to Apple. It is possible engineering and programming is getting too much done and Apple doesn't have the means to push it all out live to customers.
You cut it when you have evidence that it was wasteful.
Or, get this - figuring out what customers really want and need is super hard and churning out code doesn't solve the truly hard problems of software development.
I don't see any indication that LLMs help with requirements gathering or user studies, especially live ones.
