The more basic arguments that prevailed at the last time such an "eject" command was being considered for inclusion into usb-storage were:
1. Userspace can obviously react a lot quicker than kernel space to new or changed devices popping up.
2. Userspace works with older kernels immediately.

Neither am I. But the number of known mode-switching USB devices is now at around 50. New ones are arriving by the month or even week.
A decision to handle *all of them* in usb-storage would lead to the disadvantages pointed out.
A decision to handle just *some of them* can hardly be made plausible if there are no immediate technical reasons.
Oh, and in most cases (including your suggestion) there *are* already two drivers necessary to make these devices work, independent of where the switching is happening ...
