With the announcement and preview release of WinUI Nuget package, we are able to release and update XAML controls independent of OS Updates. We also design controls for backwards compatibility. We’ve listened to customer feedback based on our initial implementation, one being to enable backwards compatibility. Due to this feedback, we are adjusting the implementation to include Input Validation inside the WinUI Nuget Package. We are hopeful to release a backwards compatible version of Input Validation in calendar year 2019.

I voted for this feature but now I believe that it will be incorporated in the best possible way by the XAML Standard project https://blogs.windows.com/buildingapps/2017/05/19/introducing-xaml-standard-net-standard-2-0/
And I think it's the best way possible because it's not a single binary implementation that works for all platforms, but a syntactic definition whose implementation can be adapted to each platform's features and performance requirements..
Noesys, for example, is a C++ library that works very well on several platforms, but it is mainly a WPF clon. And it is good for some purposes (e. g. full-screen unity games), but here we are asking for a modern UI with a different application architecture and controls specially designed for touch gestures and mobile use as UWP.
