Ancient city feature suggestions.

My idea for the ancient city would be that you get to make one of two choices about what to do with it. One option is to remove all of the skulk blocks from the city and to effectively make it un-infested possibly allowing the original inhabitants to return and to respawn. The other option would be to help the skulk infest the city until the entire portal frame is covered, allowing the portal to open and to continue the original plan for the portal. This is just a suggestion so I don't expect this to make it into the game or to even be of value, but I hope that my suggestion will be able to inspire better idea's.
