#### Type
`inconsistency` for common use cases.
`bug` for projects relying on correct DOM emissions.

#### Description
It's unclear to me if the following is a known issue or not.
Take in consideration the snippet below:
```jsx
<input type="checkbox" defaultChecked={true} />
```
#### Current Behavior
Setting the `defaultValue` prop on inputs of other types sets both the `value` and `defaultValue` attribute on the DOM element.

When setting the `defaultChecked` prop on inputs of type `checkbox` only the `checked` attribute is correctly set, leaving the `defaultChecked` attribute unchanged.

#### Expected Behaviour
Like mentioned above, the expected behavior would be for the `defaultChecked` prop to set both the `checked` and `defaultChecked` attributes on the corresponding DOM node (like it's the case with the `defaultValue` prop).

state = {type: 'number', value: 1000};
      render() {
        const {value, type} = this.state;
        return <input onChange={() => {}} type={type} value={value} />;
      }
    }
    const input = ReactTestUtils.renderIntoDocument(<Input />);
    const node = ReactDOM.findDOMNode(input);
    
    
    input.setState({type: 'text', value: 'Test'});
    expect(node.value).toEqual('Test');
  });

    const originalCreateElement = document.createElement;
    spyOnDevAndProd(document, 'createElement').and.callFake(function(type) {
      const el = originalCreateElement.apply(this, arguments);
      let value = '';
      if (type === 'input') {
        Object.defineProperty(el, 'value', {
          get: function() {
            return value;
          },
          set: function(val) {
            value = '' + val;
