I think the biomechanical styling will reach its zenith with David's evolution, if we ever see it. Was nice seeing the ribbed corridors back in the Juggernaut in Covenant, however brief. I like the idea of David replicating/growing the bones and vertebrae sampled from the colonists/embryos in cryo and decorating his jugg or cavern with them, creating biomech/bone cathedrals on his planet. A man can dream...
