Comment:

 #30128 supersedes this report.

 So I can conclude that we can easily hit two birds with one stone here and
 close this in favor of the other one. It will be way worse if we want to
 separate these two tickets because the logic is very closely related to
 each other, so we will end in unnecessary merging conflicts that I would
 prefer to avoid.
