Servers take a lot of time and money to create and there are issues within servers that are already on the server that is being worked on so I do not think a new server is on their minds at the moment.
It would be lovely to see though, I'd love to see a minigame kind of server come up where people can earn money on there and transfer it between the minigames and the big game modes like Skyblock, for example.
Anyways, nice suggestion.
