I am glad to update that this issue was fixed in 24.0 release.
Thank you for all the feedback.

This has happened to me multiple times, and I am constantly checking ai files to prevent it from happening again, but just let one slip through and lost about an hours work. This happens with larger, more complex ai files, where I'm inclined to export a smaller sized PDF, which does not retain layer info. Meaning your work is gone forever. Very annoying. Please fix!
