These days, indie devs seem to be the only ones to still allow self-hosting of servers. Take for advantage New World Interactive (makers of Squad, Squad 44, etc). Their servers are self-hosted, though, there is an "official" license you can apply for given an application form. So there are dev "blessed" servers, but no centralization. It's what PC gaming should still be.
