Disagree. You are of course free to use whatever rate you want between
your own end points. If you want a response from routers on the public
Internet, you should *expect* this to be rate limited. I certainly
don't think that a 0.1s interval is appropriate - and configure control
plane policing on "my" routers accordingly.
