It is out of scope in terms of lens visual signature (vignetting, sharpness, distorsion, chromatic abberation, bokeh shape) because these can only be done in compositing at the moment, and even then, I find the compositing tools to be pretty limited (and slooooowwwww). This would also require to do some lens tests and recordings (not all of this information is available online unfortunately).
So it would only be a limit on the Aperture range (like f/2.8-f/22) and a focal length preset (like 50mm, or 24-105mm), and I don’t think it makes much sense to only have that? Or is it just me?
That being said, having a list of different Lens Post-Processes in the Compositor is totally doable. Unfortunately the nodes are bit limited and don’t have a way to manage a list of values from Presets (AFAIK), but you could always append a specific lens node group.
