Icicles should shatter after falling on them

Right now when placed on the floor, they basically function the exact same as dripstone. It feels more realistic if they break after 1 or more times of players/mobs falling on them. Or maybe they have a chance of shattering on impact and not dealing the extra damage to the player who just fell on them. There could also be a complexity where if you are wearing heavier boots like iron, diamond or netherite, it has a higher chance of breaking the icicles upon impact. Just something to differentiate them from sulfur spikes and dripstone so that it isn't just another reskin.
