For 3.9.0, I recommend we reconsider this change (temporarily reverting it) and consider whether an API change to accommodate the various use cases would be better
For 3.9. - I am ready to defend the patch even at the cost of the breaking of the parsing of undefined behavior. We should keep it. The patch simplifies a lot of corner cases and fixes the reported bugs. We don't guarantee backward compatibility between major versions, so I assume users will be careful when relying upon this undefined behavior and will take corrective action on their side before upgrading to 3.9.
We want patch releases to be backward compatible. That was the user-complaint.
Thanks, Senthil
