Counterparts for the new Auto-Crafter For 1.21

My idea is that we would have Placer and Breaker blocks that would basically be redstone devices that place or break 1 block in front of it automatically. This means we get drills and auto-builders. Additionally, if we could configure the Placer and breaker to an "always on" setting(the placer would just automatically place a block when there is a block of air in front of it) we could create cool mob farms with the breaker(assuming it is a drill of sorts).

P.S Mojang should increase the piston push limit and allow crafting tables, chests, etc to be pushed by pistons.

That's All Folks!
