Blazor WASM - Built-in State Management for Blazor

### Is your feature request related to a problem? Please describe.
With any large app, it comes the responsibility to manage the state of Data where the entire app can work in the most seamless way. In many cases we have "Shareable" data that can be updated at different parts of the app, and once the data is changed, certain events could get triggered and UI must be updated automatically.

### Describe the solution you'd like
We could roll our own, but this is not a trivial task and requires proper engineering. Next option is to use third party, but firstly there is no guarantee development is continued, as some of them have been dropped or secondly it could belong to a different JS framework that does not fit Blazor directly.

My suggestion/request/question is, is there any plan to have a built-in Data State Management within Blazor WASM where we can count on being engineered and maintained by Blazor team?

Thanks!
