But suppose that the changes being made are such that I'm swapping connectivity from one interface to another during the course of the changes. If I make the changes live, then there is a window where either both interfaces are connected, or where neither interface is connected, and both scenarios have implications on how I connect to issue the remainder of the commands needed to commit to the change. Maybe it is worth _also_ having the ability to queue up several changes, and apply them all at once, so that a single interface can queue up all the proposed changes and finally try out the batch, and the second interface then commits if all went well, rather than having to coordinate the handoff of half the changes being made by interface 1 and the other half by interface 2.
