Yes, it will. But I think it's justified to break the binding,
considering how much brokenness was in there and the relatively few
number of users right now.

All these patches depend on agreement of the new binding, as laid out in
patch 2/8. I don't think it makes much sense in keeping the old cruft
around given that the old binding was properly reviewed by PCI experts.

Lucas
