Any chance it could be backported > down to 9.4? If that would be acceptable, I could probably help/do that... The likelihood is zero if you mean backported into core of earlier versions.

I'm not sure if it relies on any internals not present before that would make it harder, but it would probably at least be possible. -- Magnus Hagander Me: https://www.hagander.net/ <http://www.hagander.net/> Work: https://www.redpill-linpro.com/ <http://www.redpill-linpro.com/>
