I think it would be good to get that isEditableBy logic into SQL after all. Maybe add some comments to ensure we keep those in sync in the future. But 1 or n queries for n users will make a bigger difference for a longer user list (I assume you didn’t have more than 10 users when testing?)

Also, could you make use of ARRAY_AGG and the parseArrayLiteral function that was introduced in #7479 ? (Also for the other recently added compact queries). Then we don’t have this nullable handling code with Option(x) distributed all over our codebase.
