Hm, I'd say, if there isn't a use case, and it seems likely to have
implementation and/or usability issues, and nobody has expressed a
desire to have it, then it seems fair to drop it until someone
requests it. We can copy the spec prose from the LC into a later
spec if it turns out it's needed. What do you think?
