Consider selling the required modifier in CS8618 warning

[JJLovesLife]

This required modifier is quite a good feature, especially when fixing CS8618 warnings.
However, I never know this modifier until this year's .NET Conf C#'s Best features you might not be using. I think it would be great if you can telling people there is a required modifier might fit your purpose in the message of CS8618. A lot of people would like to use this modifier!
