Which is the reason for the question. If the capability is there for one of the most basic vehicles, then why is it not there for impeller drive ships? Hell, even wet navy ships can do it.
Looks to me the impeller drive developers looked at the problem and just gave up on it and said it was impossible and that was it. Maybe somebody is going to prove the 'current' knowledge is wrong and make some new developments just like what Manticore and the IAN has done.
The Honorverse is based on the age of sail. Those ships weren't designed to go backwards either. Some of them had sixteen(or more) sails, which weren't exactly easy to turn around.
I figure the analogy is sail to node. Reversing an impeller drive would be like turning around the sails 180 degree on a 18th century first-rate ship of the line.
It would only help in a few, convoluted tactical situations in which a ship or fleet needs to make its escape by reversing course entirely. Most of the time, they go off to the side, because they still have velocity towards wherever they were going and it's easier to add side vee instead of coming to a full stop and then finally accelerating in the reverse direction.
The reversibility is utterly useless as long as it's more than a minute or two for the smallest vessels or more than 20 minutes for wallers. They can do 180 degree thruster turns in roughly those times.
