Fedora maintains binary compatibility within a specific release, but major versions of software are updated every 6 months and if the ABI is different a soname bump will happen. Unless software in the Fedora repositories flat out will not build or run with a newer ABI-release of a dependency older versions of the library aren't typically packaged. In all honesty it's virtually never an issue, most libraries maintain API compatibility and everything gets a mass-rebuild before alphas start to ship (though everyone tries to notify affected maintainers when they are going to do a soname bump on the mailing list) - so as long as you don't depend on old libraries for bootstrap of new package versions it's fine. There's plenty of compilers in the repositories that bootstrap themselves every release without giving grief, so Microsoft needs to either provide an external bootstrap mechanism again or reduce the dependencies needed to get it bootstrapped to preferably nothing more than glibc.
