Multiple end spawning platforms

There are usally multiple fortresses in the overworld, but all the portals lead to the single end spawning platform in the end. I think, this is bad, especially for big smp/anarchy servers, where a player can just build a trap, spawnkilling all the players that are going to he end. This basically makes the end on the entire server hard or impossible to join.

It also not good in case of wither obsidian farms: The player appears on the same platform where the wither must be, which may cause trouble even in singleplayer.

I think, having multiple platforms around the island (like 4 or 8) with each fortress leading to one of them depending on portal coords/chunk seed (2 fortress can lead to one platform, but any fortress must lead always to one set platform). This would solve problems with farms and will allow running multiple of them at once. For example, run sand duper and wither obsidian farm simoltaniously. And will make it much harder for one player to block the end dimension.
