Actually, it would be better to have 1:2.16 in wheezy. As Enrico pointed out a lot of time ago here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=749734 it is a little bit paradoxical that the debmirror in wheezy is not able to mirror wheezy. Will ask release managers about this and will do the backport only if they don't allow an upload for wheezy. Thanks.
