Hi
No we should not do that.
People should really not stop a route using the same thread that is
process currently messages from a route. But instead let another
thread stop the route.
There is no good solution for stopping a route with the same thread in
mid flight of processing messages on a route. Its like sawing off the
branch you are sitting on.
I have added a note on the FAQ.
