Any estimate when this might get merged? Or at least be in beta state so I can pip install the branch.

Hey @younik, many thanks for your contribution! I pulled your changes into #4571 and added some logic so that it keeps working with older gym version. That PR is now merged and the change should make it into the release this week, so closing this one.
