This looks good to me. Any chance that you can add unit tests? If not I'll do it as a follow up.

@mstruebing can you take another look?

Do we have to port it to the release-1 branch?

Thanks for the PR. It would be appreciated (but not required) to port this to the 1.x branch also.

Soon the 0.x branch will be deprecated and will be replaced by the 1.x branch.
