Pretty much all software in Fedora is already shipped in other distros which have taken this linking approach for a long time. So it is pretty reasonable to expect these kind of bugs have been identified & fixed by maintainers in other distros already. There may be edge cases remaining which no user has yet managed to tickle, but that's true of many aspects of Fedora. eg when we introduced the hardened build flags, there were places where we wouldn't know about breakage until much later. Requiring perfection before making this kind of change effectively means never doing the change.
