IMO no. Two objects with the same ID are really the *same* object,
not just equivalent for a specified purpose. (To a learner, your
chapters might be equivalent; to a bibliographer, they wouldn't be.)

Yes, but IDs aren't the way to model user-friendly names. This
email has many "names", but only one Message-ID, which is as it should
be; that Message-ID is globally unique unless there are bugs somewhere.
