Some use cases might warrant a traditional way to edit the value, compared to using the slider ring. For instance when very precise inputs are needed, but the orientation of the slider is still useful for visualisation.
You could either replace ValueText by ValueInput (the readonly prop would allow achieving the current behaviour), or make them 2 separate parts and let consumers use both.
This can already be achieved by modifying the AngleSlider, but a built-in solution would be cleaner.
