My bad, I only checked the DTS changes which landed in v7.0-rc1, and wrongly assumed the binding also landed about the same time. I think it's unlikely there are any (external) users of this binding, but obviously we cannot be 100% sure. Would it be acceptable to extend the binding so that it allows both the current and the new proposed order to coexist? Thanks, Cristian
