I think that is fine. I can understand if vendors want to first
release one or two versions that warn in error console about usage
before they remove a feature. I've definitely wanted this myself a few
times.

However I don't think the spec needs to be bound by that. So far no
one has shown *any* content which relies on callable collections, much
less enough such content on the public web that it would put a browser
at a disadvantage not to support it. On the contrary we have data, in
the lack of bugs filed on Firefox, showing that this feature doesn't
seem depended on by content.

I think we should remove this from the spec for now. It can always be
added back later if data turns up which shows that callable
collections are needed.
