 ## Limitations
 
-**This is a work-in-progress and an experiment.**
-There are considerable limitations to what is possible at the moment. For an extensive list of current limitations, please see [Temporary Mechanics](src/arcade/Documentation/UnifiedBuild/VMR-Design-And-Operation.md#temporary-mechanics).

-Other limitations might apply until the .NET 9 timeframe.
