Dead Netherwart vines (Nether Update)

OK we have a lot of vines on the Nether Update but why not add one more which in this case would be the Dead Netherwart Vine?

The Dead Netherwart Vine could be found rarely in Crimson and Warped Forest and be found more commonly in the Soul Sand Valley not being made specifically for this biome.

This vine would be created when normal nether vines are close to soul fire This vine could be placed on the floor and ceiling, it could also have spikes that would damage the player and some mobs and make the player walk slower in the same way as the Berry bush.

Thanks Mojang for reading this, sorry if this suggestion is long if you have something to change or improve, feel free!
