Just about every time I set up a new `Context.Provider`, I end up accidentally specifying a `values` prop rather than `value`.  While it's a minor error, generally I build the container in which the provider resides and commit it to the code base before I ever use it.  It's only later when I go to use it that I realize I did it again.  Since the `Context.Provider` seems pretty much useless without a `value` prop specified, I'd love it if there was a prop error if it is missing... especially if another prop is defined on the `Context.Provider` instead.
instance: null,
        nodeType: 'host',
        props: {},
        rendered: [
          {
            type: Foo,
            nodeType: 'component',
            props: {},
            instance: null,
            rendered: [
              {
                type: 'div',
                nodeType: 'host',
                props: {},
                instance: null,
                rendered: ['One'],
              },
              {
                type: 'div',
                nodeType: 'host',
                props: {},
