Since my last submission, I’ve been working on an updated version of the 
patch that incorporates the feedback received and improves the overall 
implementation. I plan to submit the revised version shortly.

Please let me know if there are any additional concerns or changes in 
direction I should be aware of. I’d really appreciate any guidance to 
ensure the patch aligns well with the current goals of the subsystem.
