Here’s the thing, the hive is a business and running the servers cost money, so making players be able to buy ranks and receive perks is a good way of funding that cost. A level based one such as the maxed in everything would be ok, but a hub title for that would be a better idea imo. Also new games being added could make that quite a bit more challenging to do.
Hive++(aka a more premium rank) is something that would work, but due to the economics of bedrock probably lack people buying it, and if not done right would make the server feel very pay-to-win.
Tl;dr free ranks wouldn’t be an amazing idea and most of these would be better off as hub titles or something. Also adding too many ranks would make it feel confusing, so hub titles would be better
