Suggestion for new/old enchantment

so projectile protection doesn't resist falling spike like dripstone or sulfur or the new ice spikes so my suggestion is to add a resistance based on the armor pieces for projectile protection helmet would have the best resistance the chest would have 75% of the helmet and leggings would be 50% and boots 25% resistance unless dropping on a spike which switch the resistance. Now to why I said new it would either be called Pierce resistance or Skewer resistance which would have mention previously and would have an added benefit of resisting spear attacks or going on to shields to resist piecing crossbows arrows with the downside costing more durability like thorns does. I don't think skeleton arrows or pillager crossbows arrow should be affected by the change in enchantment unless it's an edition to projectile protection. I came up with while watching minecraft live.
