Is this class actually used for anything in the CL yet? I don't see any actual
functionality here. =)

Yes, it is used. ProfileDependencyManager::AssertFactoriesBuilt() invokes
extensions::UrlHandlersAPI::GetFactoryInstance() (as for all other similar
factories) in order to initialize it and register the 'url_handlers' manifest
field parser.
