 ## Remarks
- In the current implementation, only one block can be transformed at a time, so this property is always `false`.
+ Prior to .NET 5, only one block can be transformed at a time, so this property returns `false`.
+
+ Starting in .NET 5, multiple blocks can be transformed, so this property returns `true`.
