Sonic Screech for renewable sand

With the recent addition of the ranged attack of the warden that goes through blocks, what if the Sonic Scream broke down specific blocks into others as it passed through them to the player/target. Depending on the current block, it would convert it into the next block as listed (or something similar) Stone -> Cobblestone -> Gravel -> Sand The Warden is indeed scary, and an awesome addition to Minecraft, so what if we added an additional use for him to be able to farm or 'break down' all that extra cobblestone we inevitable mine up 😋. Instead of an item (which was already mentioned wouldn't happen for the Warden), we give him a unique mechanic that players could look into to get sand (that's not a cheaty dupe bug). Also, you'll mostly only encounter him in the deep dark which only has Deepslate and no basic stone, so it would avoid any accidental degrading of the environment around him (it would be an intentional move to bring him where there is stone/building a stone/cobble generator. This also gives the player the incentive to not destroy ALL of the naturally spawning Sculk Shriekers, since only those can actually spawn the Warden.
