I'm not sure I would call it "baked in". FileLocator itself is just a
helper that aquires a "URLConverter" service. It happens that that
service is provided by the system bundle since it is the same code that is
used by the framework to do nested JAR and native code extraction. Your
characterization of the processing is exactly what the service does.

If that's the case, then why not just write a simple utility library
bundle that provides the code to do this? It doesn't seem like it needs
to be baked into the framework. Simply check to see if the URL is a
file, if so you are done, if not, then copy the resource to the bundle's
private area and return that file.
