Comment (by crschmidt):

 I'm okay with this, but would like buy-in from Tim because he expressed
 concern about too much magic. This magic is the kind that we've had users
 ask for, and is pretty easy to override, but at the same time, it's not
 something I want to go ahead with without approval from Tim.
