Not sure about the precise history, but I somehow remember I wanted to
use setAccessRelation and it did not work due to some cleanups that had
to take place first. You raised some concerns about
setNewAccessRelation, which motivated me to push the cleanups and I then
came to the conclusion that using setAccessRelation instead of
setNewAccessRelation is what we agreed is better.

Hope I did not oversee anything.

Best,
Tobias
