I think this is the proper way to treat games that you're done developing. My only requests might be:
It would be wild if they open sourced it. Hell I would throw money their way if they did that. Theres a good game underneath all the MMO aspects they have been trying to push. Your right, they really need a way to self host it. One of the ways Coromon (does not need MMO) and Palworld (you can do just about anything) are better options in my opinion.
