It could be neat if we ran the abidiff tool on new updates and were able to leave notes in bodhi that say "this update breaks abi compatibility" or "this update does not break abi".

ajax says in #fedora-devel that "[it could be done] with a little elbow grease. you'd need to acquire the debuginfo packages both before and after, manually unpack them, and pass --debug-info-dir[12]"

There is a much more thought out description of how this could work posted here on the devel list: https://lists.fedoraproject.org/pipermail/devel/2015-June/211160.html
