Opinions regarding from 26.4 Winter Drop (melt ice and Ice Crystals)

1. Some Light Block have been changed from "Block Light" to "Sky Light"or add 'Cool light ,Warm light' attribute.

It's really strange; ice and icicles should only melt when heated.For example, light sources like glowstones and soul torches, which don't generate heat, shouldn't be able to melt ice and icicles.

PS: "Cauldron (have lava) ,touch .fire .lava .Furnace's (use) .Campfire . Lantern" are ' "Block Light" / "Warm light" The other Light  Block are "Sky Light" / Cool light
ps : Icicle  changed to  " Pointed blocks break when exposed to nearby light (only "Block Light" / "Warm light")  sources or when placed in the Nether

2. Add more Ice Crystals's similar to Amethyst's
PS :Ice Crystal blocks ,Shard ,Budding  Ice Crystalsor (similar Amethyst) , Ice Crystals Vein (similar Ore Vein but smaller)
*Ice Crystals Vein have  75% of the blocks within the vein are not changed. Of the remaining 15% between 5% the Budding Ice Crystalsor, with the rest being filler material (Andesite). only spawn in ice cave.

3..Add Hard Ice (Immeltable ice)
If feedback 1. difficult to implement
Hard Ice can use Ice Crystal Shard (feedback 2.) and ice to carft it , similar Packed Ice but transparent have decorative brick variant .
