That's true but, the way I see USB/IP general use case, the drivers
from the host the device is physically attached to won't even be
actually used, since the host doesn't use the device. However, I can't
think of a way to enforce this.

I think the normal user just wants things *to work*. Surely, for
advanced user an option for choosing the configuration could be added
but I, personally, don't see it as a necessity at this point.

Thanks,
