Amazing!

I could recommend you to submit this as a git patch with contexts and
futher explanations to this mailing list (outside of this thread
context).

This is not a MR based workflow as in Github/Gitlab. Patches are the best
way to start futher reviews and analysis. Maintainers and volonters will
try to give returns back as possible.

And maybe, someday, we will have a new official release, maybe ;P
