I just noticed this doesn't handle a missing/ empty setting correctly. I'll push a fix.
Update: while writing tests I noticed we don't handle this correctly and opened #71439. I'll return to this PR once that is merged.

This looks good to me, I'll take another look after #71439 is merged but I assume this PR doesn't change much with it. |
