Villagers trade Grass Block

For years now I have been annoyed about villagers not trading Grass Blocks. Mostly because this would help out different world generation types when it comes to obtaining grass without cheating. 

Stone shore and Stony Peaks biome only worlds can not obtain grass blocks in any other way than cheating it in with commands. I have spent the last 3 years checking structure generation and villager trades to see if anything can be done without cheating with commands.

Making villager trade grass blocks can also help people who make youtube videos where you only live in 1 biome or 1 dimention to obtain grass and get regular mobs spawning.
