Yes being able to import SVG images and not bother about their size while being able to resize them at will inside GIMP while always have the perfect render is definitely one of the use case I had in mind when I implemented this. This already works in my code.
Actually look at the demo video I made in 2020, as I demonstrate exactly what you talk about (resizing the link layer re-renders the external SVG at the target size): https://www.youtube.com/watch?v=N5oyqbD7zyQ
