Only "sensible" alternative to *automatically* install itself, that is.  It
could, of course, require that you turn it on manually through the CDA menu...

And the Toolbox Reference *does* say "The second entry point is necessary
because CDAs can spawn background tasks that rely on the availability of the
current ProDOS.  The shutdown routine allows the CDA to stop the tasks."

And NDA's *should* get their grubby fingers out of the system on a ShutDown.

Oh well.  Arguing for the sake of arguing :-)
