I mean something like for example new set,
create_shared_action..
I mean new total new commands.
Does it make sense?

I fully agree with you, the question is how to do it,
since in some cases it is jut one line of code,
and in other cases it can be much more complex for example raw_encap,

I think we should think how we improve the examples in the rte_flow context,
