It seems that the built-in compiler could start magically transforming “@undefined” instead of magically transforming “undefined” any time we like; likely a simple find and replace job. Or it could do both during a transition period. It could even treat a bare “undefined” as an error if we are worried that we will make that error.

Yup.
