Check for interface existence in wfLoadAllExtensions() too, otherwise if an extension comes with an interface [e.g. BookInformation], the require() can cause it to be double-initialised (the implementing classes will have been loaded, which will have caused PHP to autoload the interface definition) leading to a fatal error
