You say that, but there are ~5 people on each side
woh've expressed an opinion on pinning one way or the other.
And the original consensus call did not even esk the question
at hand.  Rather it was whether to specify pinning or not.
Not whether to reserve space to do so later.  Subsequent
discussion has been the same echo chamber of Eric, Rirhard
and you on the one hand, and Paul, Nico and I on the other.
Perhaps at this point we might actually hear from some others.

Here I agree, but things like unaddressed downgrade attacks are
also a factor that is supposed to tilt the scales.

The story is quite consistent.  Applications that have no need
for pinning pay no cost as claimed.  Applications that need it,
can't use the present specification at all, but would be able
to at the cost of storing the pins, and requiring the extension
when pinned.  Nobody pays an extra cost they could otherwise
avoid.
