Generative PBR/normal maps for blocks/water. Shadow quality scales with RP.

This would help with compatibility with resource packs old or new, bought specifically on the marketplace or downloaded elsewhere.

Shadows could scale with the resolution of the pixels set for the blocks or water within a resource pack

(a 16x resource pack would be the same as default while a pack with 32x textures would have the shadows and normals matching the set pixels of that resolution)
