Positioning

[Apples]

I have an idea that I have discussed with a good friend of mine. When a player crouches he is 2 (height) by 1 (width). It would be a great digging idea if you could do 1 (height) by 1 (width), so that the player is basically lying on his stomach and
moving. But, the rule is you can only use shovel while digging lying down. This would increase strategy by a huge amount. Please consider my idea.

How realistic, somebody lying on their stomach while mining and digging.
No.
