The reason why you cant use TinyWE or teleport in the nether is easy. (I think I said this before)
But we wanted to keep some of the 'real' nether alive. So it is supposed to be a scary dangerous place, where you have to watch your step.
Making TinyWE/Teleporting work in the nether would defeat that purpose.
Would it be any fun if you could just walk around there and don't have to worry about dying?
I've seen some creative things in the nether made by players. And I can remember the thrill from back when I was a player.
Making something, not knowing if somebody would rob you blind, hiding your chests, making traps & hidden rooms.
Think about it.
Also, I got a couple of lots in the nether, most of them where once a spawn.
Look around on the map.
