Seen from first principles, BVH is quite close to some kinds of hierarchical clustering. The ray intersection part can be understood in turn as a kind of normalization, or projection to the unit sphere. So depending on how much hardware is actually reserved to this task on-chip, there might be ways of making it somewhat useful in the ML context.
