Growing Pointed Dripstone

I think pointed dripstone should very slowly grow if it is placed on the ceiling of a dripstone block, and there's a water source block above the dripstone block. It would drip water to indicate that it's growing, and if there was dripstone (either block or pointed) directly underneath the dripping stalactite, it would grow pointed dripstone stalagmites underneath it as well. Stalagmites wouldn't grow if any other block besides dripstone is underneath, so it wouldn't affect cauldron collection.
