I have updated this PR to point to the new lts/1.20.1 branch for backporting. I will likely try to port this up to 1.20.6 first - see if any modifications are needed to this PR and then merge this once that is done (to maintain feature consistency). Thanks for your work on this, and I hope this won't take too long to get to.
