Why "default"? Is that an out-of-the-box default queue name in Rabbit? Perhaps we should choose a more shove-specific name. I'm reaching a little, but I could see some unrelated Rabbit lying around with a queue named "default" and Shove accidentally trying to execute commands from it. (I hope most of them would fail due to not matching the whitelist, but better safe than silly, and it's an easy thing to change at this point.)
