While I agree that it’s bad form, at least for FreeBSD it doesn’t make any 
difference for the packagers.  We will rebuild all of the packages that depend 
on -base when there are any changes to the -base library, whether the SO 
version has changed or not.  

It takes less than 24 hours to build the entire 30,000 package set on a single 
machine these days and it’s far better to burn some cycles unnecessarily than 
to ship a package set with ABI breakage.  Even if the ABI is backwards 
compatible, there may be changes to the headers that will cause dependent 
software to enable new features at compile time, so skipping a rebuild is 
usually a bad idea.
