Ore Generation with the Caves & Cliffs Prototype Data Pack

I know this is more of a bug with prototype, but there is no spot for reporting bugs on the issue tracker for this prototype datapack. If there is a better place for me to post this please let me know.

Diamond ore (and presumably other ore generation) does not generate at intended heights, possibly going off of old extended world height levels. Using commands to replace stone with air, I've found diamond ore veins as high as around y=58 with a seemingly equal distribution at all y levels below that point. In short testing on 21w16a without the datapack diamonds do not seem to spawn at high levels.
