Ah, now I remember you told me about this previously (more than two and
a half years ago).  As I said back then, if this requires changing how
todo-mode entries are added to the fancy diary display, it may take some
effort.  But if the consensus is that this is a good change for Emacs,
then I'm sure todo-mode can adapt to it.
