We, as a distribution, haven't solved the problem of ensuring a) Packages which dynamically load a shared library are rebuilt when appropriate b) After such a rebuild, the package loading the shared library and the shared library are upgraded together while still avoiding the use of hard Depends (since they defeat the purpose of dynamically loading a library). This has been solved for programs which just dynamically link libraries through binNMUs and symbols/shlibs files, but we really need a similar mechanism for dynamically loaded libraries.
