Ultimately the rule of thumb is if it's a soname bump you need to
rebuild all the packages that are dependent on it when you push the
build. Relying on the possibility that some time in the future there
maybe a new release of something is not good enough as there are
people that use rawhide constantly and you're unnecessarily causing
pain for them and extra work for others to cleanup the mess. If the
soname is bumped you need to rebuild all the dependent packages no
matter what even if tomorrow or next week there will be new releases.
