Looks good! Are we waiting for anything?

@MartinHjelmare Seems like it's just a typo in the PR description.

[MartinHjelmare]

That's been edited I think.

[gjohansson-ST]

@MartinHjelmare actually the config entry was merged just after the .4 release so it wasn't part until .5 release hence I set this as draft so it's not breaking until .7 e.g. 2 releases.

But now beta has come out so we can move on. Same for #93547
