There's an easy fix for that:
yum install apt
This yum misdesign is the problem, not the soname changes.

The update will be done (doable at least, see above paragraph) a few hours 
later when the reverse dependencies have been rebuilt. Compare this to the 
compat packages situation where packages can be running against the vulnerable 
version for months with nobody noticing (no "broken dependencies" report, for 
example). Also, I want vulnerable packages the h*ll OFF my systems, not put in 
a compat library!

I also generally don't want to have 2+ versions of each library cluttering my 
hard disk, I want the packages to be updated to work with the latest, and 
compat packages encourage exactly the opposite (and if I hit the hopefully 
short window where the package is not rebuilt, instead of the library being 
held back by apt-rpm, I'll get a compat library installed which will become 
unnecessary only hours later, what a waste).

As for packages outside of Extras, I don't see why they shouldn't be rebuilt 
too if Extras changes. As a packager of a few unofficial RPMs (which need some 
cleanups before I can consider submitting them to Extras), I'll definitely 
rebuild my RPMs as quickly as possible if a soname change in Extras requires 
it, I don't see why Extras should be forced to provide compat libraries just to 
allow me or others to be lazy.

It can be solved much MORE simply by not introducing the compat library clutter 
in the first place and just doing 1).

That's not something Extras can fix, so it's pointless to discuss here.
