see #4260 for ongoing work. Shall we close this as a duplicate?

  • Status changed from needs_review to positive_review

Martin suggested to close this ticket as a duplicate of #4260, and I agree. So, I'm inserting Martin as a reviewer and change it into a positive review (with the suggested resolution "duplicate").
