@NL66278 For clarity to other reviewers, could you edit the description of this issue and add a checkboxed list of PR's that you are forward-porting with this PR?

Also, could you remove the first commit, because that one is already part of another PR.

@thomaspaulb When the other PR's are merged, I could rebase this one. Or alternatively when this one is approved we can have all the improvements in one go.
