The RPC arg is not a dummy, but a label, so offering an undocumented alias is inconsistent with all other label interfaces and confusing at best, if not entirely unused.
Fix it by removing the deprecated alias.
This pull is a breaking change, but it should be limited, because it only affects someone using the deprecated named arg on this RPC. I can’t imagine anyone doing this, because in all other places where label args are accepted, they are called label
. If someone really didn’t use label
here as named arg, it would be trivial and less confusing for them to fix it up.
