That is what you told me to do!

https://lore.kernel.org/stable/YQEvUay+1Rzp04SO@kroah.com/

I would happily adapt my script, but there's no
good/documented/working way to determine upstream commit given -stable
commit.

If we could agree on

Commit: (SHA)

in the beggining of body, that would be great.

Upstream: (SHA)

in sign-off area would be even better.
