(hey I found the template without the form)
Currently the "biome has that ore" tags just manually contain the standard aether biomes, but that means they don't contain biomes from addons like ancient aether/deep aether/aether redux. It's especially an issue cause ancient aether adds a cavern biome (holystone caverns) at the level where these ores would generate.
Could be fixed by changing their content to refer to the aether:is_aether tag (but keep them separate so they can be configured with datapack like right now.
