Example:

const [valueFacet, setValue, valueRef] = useFacetState(0)

This would be equivalent to doing

const [valueFacet, setValue] = useFacetState(0)
const valueRef = useFacetRef(valueFacet)

But then there would be no need for useFacetRef do use a useFacetEffect, instead updating the ref could happen in the setter. This would help with performance, and make the type of the ref cleaner (since it can't be NO_VALUE in this case)
