Yup.

To the best of my knowledge, all those passes are optimisations only and should not have been used for anything other than that, either by design or accident. If they did, it's a serious unintentional bug.

Also, this is a simple patch, and if you do find anything on your side, just let us know and this can be easily and quickly reverted, but a bug needs to be created to address the issue.
