@moritzstaffel I have rebased and resolved conflicts here. I test rebased in onto main and it applies cleanly. As i rebased it, it will be applied with correct date and attribution at the an of the commit three. Question is whether we need all the separate commits or if we want to squash the commits (attribution will be lost, unless we add Co-authored-by: to the squashed commit itself). What do you think?
