When multiple plugins of a given type can provide the same feature we don't have any built in and generic way to prioritize them. It would be nice if the plugin could declare in its meta-data a priority, that the loading machinery uses to give consumers of the factory loader a priorized list of plugins.

We don't neccecarily have to sort the libraries/staticLibraries, but the keyMap and other helps could have versions that return an ordered list of keys, that the consumer then maps to a loader index via loader->indexOf(key)
