My maxim: is "it" intrinsically the same, or coincidentally the same? Intrinsically the same means a rule, and so there should be 1 source of truth for it. Coincidentally the same means it has the same shape but this just happens to be the case, and they should be left separate to evolve independently. Ultimately, it boils down to really thinking about the domain.
