I understand the matter in theory, but I don't understand the matter in practice. Clicking through on the user, I couldn't identify any machine-translated overwrites of his work. What is an example of this? And if the community that manages the site objects, why not apply a batch temporary revert, and then re-run once/if everything is solved.

This is a trivial operation for me to do on MediaWiki with a bot, so it must be straightforward to do here too. I think "Ask forgiveness, not permission" is fine in order to move things forward, but you do have "ask forgiveness".
