It was a idea that came to us when we found many skeletons spawners in a hardcore no regen world. (personal server with friends)
Now this is a pretty broken idea honestly but it did sound kinda instresting it would make the player create a piston based block transportation network to transport large numbers of mob spawners to a central location aswel as this did lead to the discussion of using it for chests to transport shulker boxes or other items around but rail way or flying machine is always easier for those applications.

I dont know if this is possible already through changing some values through a datapack as I am not familiar with any of such things
if this is already possible through the use datapack in combination with carpet movableblockentities I would like to know more about this.
technicaly speaking the mobspawner is a tile entity but still acts as unmovable block so Imagine it eiter misses a tag or the code for movable block entities has a hardcoded list of blocks reguardless it would be a cool experimental feature that might at home in either carpet or the carpet-extra addon.

Will be added once #1120 is merged
