Next the rules will produce code which is statically kind Protected, has no resource leaks, and catches quite a few a lot more programming logic mistakes than is prevalent in code nowadays.
If we have 1,000,000 traces of recent code, the thought of “just transforming it all at once” is often unrealistic.
