@mkurnikov any progress on this? :)

I have very little time for Python development now. I'd only probably find time to finish it (and other PRs) if there's a big need from the community, otherwise, I'll just postpone it indefinitely.

Could anyone add a thumbs up on this post so I could understand how many people actually need it?

This can probably be closed in favor of #1025
