Thank you for your post!
When it comes to the Microsoft Information Protection (MIP) SDK supporting the debug symbol, I'd recommend creating a feature request using our User Voice forum so our MIP engineering team can look into implementing this feature.
If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
