What's the purpose of adding `TypeForwardedTo` attributes? about polysharp HOT 2 OPEN

In case you generate attributes as public in lib A and have reference to them in another lib B (or generate as internal and use reflection).
With this attribute lib A will always have definition of IsExternalInitAttribute (real or forwarded). Without it, there is a possibility of TypeLoadException in some edge cases if A and B are updated separately, but I wold say in any sane deploy scheme this should not be a problem. Or maybe I missing something obvious.

Like if you publish lib A ver 1, but in ver 2 change PolySharp settings, so this type is no longer generated.
Lib B is transitive dep of app have dependency on A.v1, and app have direct dep on lib A.v2 -- assembly redirection would kick in and choose A.v2 and lib B will throw TypeLoadException.
