> Currently, if the same URN is registered twice, it results in an exception. Instead, if it is a duplicate registration (for example, caused by double-shading of the service loader config) it should succeed. This requires probably good equals methods for the rehydrators.
> Other minor issues: it will fail at load time and from then throw class not found errors, which is extremely annoying. It should instead load lazily so we can always get a good stack trace.
