…cols to a warning. Previous compiler versions allowed this, so we should stage the change in as a warning. This was already a warning across modules, so this change only impacts redundant conformances to marker protocols within a module. This code also isn't particularly harmful, because marker protocols don't have requirements, so there isn't the same risk of unexpected behavior as other redundant conformances.
