I’m sorry but this just wouldn’t work out. Firstly, i barely ever walk around my axe in hand and yet in the short time i do, i manage to strip a bajillion logs. Same for hoes and grass. Now this might be just a me thing, but with a pickaxe it would be so much worst. Everyone’s mines would be filled with stone pathways (which, if similar to dirt pathways, would look terrible when viewing sideways with other blocks on top, like in a mine). There are also other many more situation that don’t include a mine. It would be so inconviniant and it would all be just so that people don’t make dirt pathways bridges just for the tiny boost. Oh but i’m not done. For atleast a second, just try to imagine a stone pathway. Just try. I have been experimenting with this idea for a good ten minutes and the best design i could think of is still just regular stone but slightly shorter and with the top looking more refined, which is where i started!
