Borrow-checking the dereference of a stale pointer won't be worth much, though.

Sure; but I bet raw pointers are used very infrequently in the new codebase. The code was ported from zig to rust. I bet a lot of pointers became rust references in the process.

		That’s my whole point! It’s ported to unsafe rust, not default rust.

		The point of compiler-based checking would be that you know for sure. If you have to bet, all bets are off.
