I would rather just have the behavior for that variable “append mode”,
period. Maybe do it generally for all multi-value variables. It would be
like “add only” permissions - if you don’t want something loaded it cannot
be specified ever, overwrite is not allowed. Get rid of any
order-of-operations concerns.
