Moving this file looks overdue, but I wouldn't do it in a revision (and actually not even in a minor release), so I think we should decide how to handle the next release. Will master become 2.3.1 or 2.4?

but I wouldn't do it in a revision (and actually not even in a minor release), so I think we should decide how to handle the next release.

So it is better to leave it to GD 3?

Will master become 2.3.1 or 2.4?

Sure. We have milestone list.
