Please add this plugin as it offers the enhanced capabilities of subservers which allows bigger servers which will prevent you from using different individual servers. Like most servers, you can right click an item in your hand and you will access a GUI to select a server (survival, creative, KitPvP, etc). This will allow Aternos users to make more advanced servers.
This is used by about every other big server in the world (some use a different way but this is easier).
Seriously, although I've seen the previous topic, I don't see how it would break the network. I am opening this because I am confused and I don't think it's fair that people cannot utilise the full capabilities of Spigot due to their server host refusing to allow some plugins and though you may assume it can break the network, it may not.
For reference, here's the previous topic:
