Preferred instance lists should dynamically update with published library updates

In File A I create 20 (arbitrary example) different components that have an icon instance property. File A has access to my Icon library (in another file).
So I add all icons as preferred values for my 20 instance props in File A.

Now I add some icons to my library and publish the update. Well guess what? Now I have to go through the 20 props in File A to manually add those new icons as preferred value.

Imagine this at the scale of a mature international design system. What’s the point of the preferred values feature then?
