The challenge becomes what code to emit when you see those operators: native target comparisons, or the software implementation of your total ordering? The latter is safe and slow and the former is fast and IMO idiomatic.
So since no one needs this often enough to emit the soft-float comparison code, we should emit the fast code. If folks need different behavior they should use different types. This is similar to the behavior with integer overflow, which you can opt into by using checked types or checked operations. Though in rust we have a convenience that the overflow-detecting code is emitted for debug targets.
