you probably know that you can place blocks above the nether but not mine them, I've read that this is an intended function and I think that's just asinine.
there's no reason to limit building above the nether, the PC can do it. there's nothing actually stopping us except the annoyance of having to remove blocks with TNT. But, the hindrance shouldn't be there at all, there are a lot of great farms that only work above the nether and with our spawn cap being so low these are some of the most viable options for gold farms, ghast farms and XP farms. all of which are borderline useless inside the nether cube on console due to the spawn limits.
