sandstone into sand? using anvils

hi! idrk how this works but- id like to suggest something a *bit* related to one of the similar posts to this, but not really..? my suggestion is that,taking real-life physics into consideration, if an anvil is dropped onto a sandstone block, a random number of sand blocks (dropped as items) drops from said sandstone a cool addition to this could prevent abuse of this method- after a few anvils are dropped onto the sandstone- say, 3-5 times or so- the sandstone breaks into a single sand block item. anywho- yeah thats it :> buh bye
