@evrimfeyyaz: thanks for submitting this PR! I'm sorry it's taken me so long to get to it. Looks great to me. After more consideration, I think this is potentially a breaking change for some people, so I'd prefer to release it as part of v5.0 rather than v4.0. I've gone ahead and merged your changes into the 5.x branch. Thanks again for contributing!
