I’m not misunderstanding, it’s just clear that they have virtually no requirements. As soon as you have any meaningful requirements, this entire architecture probably falls apart, let alone the fact that you can’t hire for it, as no one is going to want to work on your obscure game server.

The criteria are also so brittle at those concurrent numbers that if the game decided to do any more than what they do today, you would face engineering challenges more difficult than other game server software.

As you deal with more and more concurrent clients there are calculable limits to how you can facilitate more features and how bandwidth and server frame time budget limits you.
