I don't think it'll make any real difference: in both cases the old code
won't work anymore: I'm hard pressed to think of a scenario where the
"subtle" behavior change is subtle enough not to be detected
fairly quickly.
For example, code such as '(` foo) would change behavior. Whether a certain list is nested or not is definitely subtle enough.
