The problem with that approach is that lots of bugs go unnoticed until
very late in rawhide, resulting in those bugs being caught and fixed
only post-release. ABI. That is, any ABI breakages that happen
are usually bugs. We try to ensure that with a basic ABI checker in
the glibc testsuite and in future we'll be looking to enhance our ABI
checking capabilities. Taskotron (based on a quick read from the
wiki) seems to be a good framework for this.
