At the time of filing this issue we don't have a branch that yet targets 6.0 so this can't be worked on.

hey @nik9000
Now that #19633 is merged, I would like to have a go at implementing the remaining enhancement. I figured I will ask before doing the work, as the issue does not have an adoptme tag.
Thanks!

@olcbean it is all yours! Thanks for asking! I'd totally forgotten about it.
