The Cherry Grove Biome is not listed in BiomeTags.STRONGHOLD_BIASED_TO. This tag is used during Stronghold Generation to shift the location to specific biomes if they are in range. The other missing biomes in this list suggest that the main purpose is to shift the Stronghold away from water biomes onto land. Cherry Groves will likely have one of those biomes in their vicinity, which would lead to Strongholds not being able to generate in a Cherry Grove Biome.

This seems to be related to other times where Cherry Grove was not assigned to expected biome tags: MC-263202 / MC-260409 / MC-264948
