..but you can't just use one library to replace the functionality of a framework. While a library has "more degrees of freedom", this means your application (using many libraries) has many moving parts that don't really care about each other, so your application -- already octopussy because of having to glue libraries together in the first place -- now gets even curlier as you tweak it to fit library changes. Framework developers, one hopes, at least try to keep their changes-over-time a bit consistent within the framework. Library devs have no such obligation.
