I don't know why people think that legs automatically make everything more flexible. It boggles the mind.

Look at real flexible manufacturing systems to see how much of a bullshit idea that is: https://youtu.be/gUvE2eFH6CY

Everything is transported via the central stacker crane that is directly connected to every machine. You don't need legs. This just leaves the arms and here is the thing, you can just have two robot arms in the same robot cell and call it a day. The humanoid form factor adds nothing.

Also what makes you think you don't have to program the humanoid robots? Again, everyone seems to think that if you build a human shaped robot, human level intelligence will automatically come as a result of the shape of the robot. The moment you remove the head, the intelligence vanishes.
