@fmayer Thanks for feedback! Do I get it right that you want me **not** to merge the PR until @pcc looks through the changes? Alternatively, I can merge this "as is" since we already have an approve, and, if there are some issues, just submit a follow-up patch later. This one is a prerequisite for PR94241, so it would be nice to get this merged relatively soon.
