This sounds very useful!  Ideally, we would run this tool
automatically for the OS core and ABI changes would require signoff of
some sort, and unless absolutely necessary were reverted.

Tools like this though are at their most effective when they catch
changes upstream not long after they're committed, before downstreams
have at some indeterminate time incremented integers in .spec files or
equivalent to distribute the changes.
