I'm all for more kinds of tools as well. Preferably new ones you can craft by gathering lots and lots of resources so it takes time to earn them.

And yeah, it would be nice if mining at a higher physical level gave you one or two more pieces of iron / stone / nuggets than usual. It works for digging up vegetables, so why not minerals?
(Not proposing that it should work for diamonds, though. For obvious reasons.)
