Hi Nicolas,
We actually have a community pull request that will add the same Rename module functionality for authority records,

I have not yet managed to 100% confirm with our Maintainer team if they intend to include this in the upcoming 2.8 release or not, but I suspect so. It appears that it has already been code reviewed and merged into our main development branch, which is a promising sign!
In the meantime, it will not be fast if you are hoping to make many changes, but you can use SQL to edit the slug of a record.
