I see.

I don't mean to remove that restriction.  But in this case, where the
parent is deleted and the child is the parent's minibuffer-frame (and
there are no other frame using this minibuffer-frame) this restriction
doesn't seem to apply, at least on a conceptual level.

From the point of a user, this means that he either needs to advise
`delete-frame' or use a different command in order to delete these kinds
of frames.
