I don't know the answer, but I suspect it lies in turning the question around:
why should { have that definition?
I can't answer that one either, but apparently it has appeal. You're in quite

I personally don't favor it, because today's definition makes certain classes
of bugs obvious, and the proposed one would make them subtle.
