I think the PR is still relevant and there hasn't been many changes on the
Table API batch side. So it's probably not (very) outdated. Unfortunately,
there are many things with higher priority at the moment (which might change)
such that I don't have time to look at this.
Thanks for keeping the branch open @chermenin!
