> A lot of algorithms and data structures rely on nondeterminism for performance or security (by default). It is too easy to introduce nondeterminism accidentally.

You don't know what you're talking about - no compiler engineer in their right mind would intentionally use a randomized algorithm in a compiler. It's a bug every single time and it gets squashed immediately.

They won't use it intentionally, but it is not like it can never happen. E.g., https://reproducible.nixos.org/nixos-iso-minimal-r13y/ is still only 96.59% reproducible.
