Wouldn't it mean effecitvely ending up with only one command (in

them.

yes, I have been stuck on that as well.

There are a number of RTA attributes that are only valid for GET
requests or only used in the response or only valid in NEW requests.
Right now there is no discriminator when validating policies and the
patch set to expose the policies to userspace
