The wooded_badlands_plateau and other sub-biomes still generate instead of the wooded area being height dependent. This leads to the area not being in the right locations. The issue with sub-biomes not being removed is already being tracked as MC-236800. This issue is that the wooded area of badlands biomes it not generated properly.

I can confirm the fact that they no longer generate only on plateaus, even though the biome name still has "plateau" in it is a bit misleading (same with jungle edges not being edge biomes anymore).
Whether this generation is considered incorrect or not, i don't know.
