The places I would have found this most useful are in a super() invocation, where you simply can't write a local variable before Can we just lighten the restrictions on what you can do before calling super()? I know the VM already supports it.

Not easily. It would require adding a whole new set of definite-assignment-like rules to ensure that super() gets called exactly once. Currently, the rule is that if the first statement isn't a super call, then super() is implicitly inserted.
