PBR depth parallax?

[PixelWAD]

Recently I've been trying more and more PBR textures and it feels like a future. However, what I'm still lacking is a depth to these textures - no matter how I look at them, they still look flat. Eduke32 has x parallax, y parallax commends available to add depth. Is there any chance to add this to gzDoom? This way we could replace flat rock walls, with actual rocks that some some depth upon viewing from different angles.
