Expanded use of dispensers (Java)

I feel as though expanding the use of dispensers would be a great addition to the game. More specifically I would like to see various blocks that would normally be only obtained in survival by a player interacting with that block with a specific tool. I feel like this would further open the doors to automation in the game.

How it would ideally work...

When a corresponding tool is placed in a dispenser next to a block, the tool's effects will be applied to that block.

This change would affect blocks such as

-Grass Blocks
-Pumpkins
-Logs

We already have this for shearing sheep, so why not this? The (albeit low) amount of work for a change like this would be a great step for this game.

Thank you
