This is intended to be paired with the new combat snapshots featuring stackable potions. A lot of players have expressed concerns about this making potions over-powered.

But in order to have a large amount of potions come into play, you need, among other things, a large amount of Nether Wart. But what if this was just a little harder to get?

If Nether Wart can only grow in the Nether, or if it grows much slower in the overworld, then having several stacks of potions becomes something that requires facing a much greater threat from ghasts, lava, and other dangers than it did before.

Building a Nether Wart farm in the open, say in a soul sand valley, would be fast and probably look pretty cool, but is also risky due to mobs. Tunneling in somewhere to make it underground would take additional time and effort, and still carry some risks.

This also encourages players to spend more time in the Nether, and maybe even build bases there to make the process safer. After all the cool new features from the Nether-update, this seems like something we should encourage.
