I'm not crazy about those wp- prefixes but for now it's not a problem if we want to change them in the future. We should just be mindful so that this "internal" name does not get stuck like FSE (Full Site Editing) did 🙂 .

Reading #37, it seems to me that the whole purpose of this PR is to avoid sticking with a gutenberg- prefix (in favor of wp-) 🙈
