Would be nice idd. I don't see a reason not to allow this but ofc it's a minor issue so if it's really a lot of work to allow any modification of locked items, it wouldn't be worth it.
I would definitely like this! The only conflict I can perceive is with repairing on the bench vs salvaging: Locked items may be blocked from the bench to prevent unintentional salvaging. I can't think of any other conflicts.
