We can document it alongside broadcast and broadcast_arrays under array manipulation routines, which would make it at least as discoverable as the standard broadcasting functions. I'm not opposed to adding extra_shapes as a keyword argument to broadcast_arrays, but it seems unnecessarily complex, Implementation wise, I think it would actual make more sense to make broadcast_arrays depend on broadcast_to (e.g., by composing a function to calculate the broadcast shape with broadcast_to).
