Stalactites break off and fall if they grow too long or are made too long

When stalactites grow longer or are made longer than 16 blocks they'll break off and fall to the ground because they can't hold their own weight onto the ceiling. This idea could be blended in with stalactites randomly falling if they're naturally generated and not connected to a dripstone block. The longer the stalactites are, the more unstable they are (until they're longer than 16 blocks which is when they'd have to break off and fall). When the stalactites are connected to dripstone or placed by the player, however, they will stay stable up until the 16 block limit, but if it grows longer or is made longer than that it'll break off and fall. Hope you guys find it useful!
