It looks like this backport needs a review, if someone would be so kind.

Thank you!

[PeteGillinElastic]

Thanks @pquentin . Out of interest, is make contrib something I should have known about myself? (I didn't do it on the PR on main, but I think the bot came along and updated the specification output afterwards.)

[pquentin]

Yes automation takes care of it on main, however I was not sure it would work on a branch so I ran it just in case. Not something you should care about yourself.

Thanks for asking!
