Thanks for the patch! This is an interesting issue. One thing I am not sure yet if this has potential to clash with the other stride versioning logic in LAA.

For that particular case at hand, I think we may not need to version, as it looks like the wrap flags get dropped during `IndVars` before `LV`, but we may be able to retain the flags. This is something I am currently looking into.
