I am not quite sure if I agree with (or understand)  everything you

this is basically what I was trying to get at, but put much better.

I see it as somewhat of a balancing act.  We don't want to give
information that another layer just cannot do anything with, but we also
don't want to get too narrow or prescriptive either.
