When I rerender a component with "defaultChecked" or "defaultValue" react fails to update the "value" and "checked" attribute accordingly.

Before you say "use a controlled input" I would argue that this is a bug as it basically disallows uncontrolled forms with "reset" buttons. (It will always reset to whatever the initial default value was).

this.updateTextContent('' + nextContent);
        if (__DEV__) {
          setContentChildForInstrumentation.call(this, nextContent);
        }
      }
    } else if (nextHtml != null) {
      if (lastHtml !== nextHtml) {
        this.updateMarkup('' + nextHtml);
      }
      if (__DEV__) {
        ReactInstrumentation.debugTool.onSetChildren(this._debugID, []);
      }
    } else if (nextChildren != null) {
      if (__DEV__) {
        setContentChildForInstrumentation.call(this, null);
      }
      this.updateChildren(nextChildren, transaction, context);
    }
  },
  getHostNode: function() {
    return getNode(this);
  },
  /**

  unmountComponent: function(safely) {
    switch (this._tag) {
