This makes diagnostics more verbose and accurate, because it's possible to distinguish how many parameters there are based on the message itself. Also there are multiple diagnostic messages in a format of `<descriptive-kind> <decl-name> ...` that get printed as e.g. `subscript 'subscript'` if empty labels are omitted.
