Yes! Agree completely. I recall this behaviour stumping me on
several occasions in the past, though any specifics of what I was
trying to do are lost to the mists of time.
Furthermore, I will venture that in all instances of breakage, it
will be not because the broken modules functionally rely on this
behaviour, but because they go out of their way to cope with this
eccentricity. Fixing such breakage will boil down to a removal of
make-work code (which may still not be trivial, naturally).
