F-delta and Fmaj7 are two different ways of displaying a chord named "F
major seventh."

On the other hand, Dm7b5 and D0 are two different names for the same set of
notes.  (But both of those names are listed in the Dolmetsch reference for
that set of notes).

That may be a possibility.  However, I think that the exceptions method is a
workaround, rather than a solid means of naming chords.  In particular, I
don't think that the exceptions method will work for slash chords.

Yes.  That is why I want to separate naming from displaying, as much as
possible.
