When might you want to use such a thing, as opposed to having :type a
static list that encompasses all possible valid settings?

I can only see it being harmful. Eg if you want to compute the :type
based on whether some external utility is installed on the system, you
could end up with saved settings in ~/.emacs that suddenly become
invalid (wrong type) if said utility gets removed from the system.
