Sure - but converting SVG to FXML is definitely not the most efficient way to load a scene graph from SVG.

Base on your response to #2, I see it is useful to use the URL as a key to looking up in the cache, but the more generic possibility of FXMLLoader.load(java.io.InputStream) would open a few doors for developers where now they must climb in through the window.

I'm not sure what you mean by this. FXMLLoader does define a load(InputStream) method. Either way, I don't see how that will help you load an SVG document more efficiently.
