Are kernel verifiers over-relying on bitwise equivalence to PyTorch Eager?

- Quoting Edward Z. Yang's new post "PyTorch: a reference language", which frames PyTorch as the lingua franca of models: a reference implementation is a simplified but complete version of a system, and PyTorch's APIs and conventions form a "reference language".
- The author finds it amusing that kernel verifiers all goal on bitwise equivalence to PyTorch Eager, effectively presuming Eager is the gold standard of numerics.
- While true in some sense, that assumption often doesn't hold — making bitwise equivalence a questionable verification target.
