Thank you for the answer.
On the list of pages, when I hover on a draft, I do not see the “revisionize” link. It only appears for published posts.
We do need to create a revision of a post that has never been published before. That’s because we need to let a third party work on the draft, and then review it before the first publication.
I did not notice that accepting a revision publishes the original post, but that is going to be an issue too yes.
Thank you
