@ydah JFYI:
I get feedback from @nobu. nobu suggests it's good if we can reduce redundant <node_args> specification on caller side. I think it might be possible to introduce new Lrama grammar file syntax to support default LHS type specifier on %rule definition like below, which will be overridden caller side tag specification.
As a fact, all these 3 PRs use same tag

• Use user defined parameterizing rules opt_args_tail(tail) #10667 uses only <node_args>
• Use user defined parameterizing rules f_kwarg(kw) #10669 uses only <node_kw_arg>
• Use user defined parameterizing rules f_opt(value) #10670 uses only <node_opt_arg>

%rule opt_args_tail(tail) <node_args>: ',' tail { ... } ...

#10706 removes redundant <tag> specifications on caller side.
