That's what I've been wondering. If it's a possibility we should handle it somewhat gracefully. But I struggle to see us selectively handling certain types with V and others with P, so I reckon we'd just make a top-level all-or-nothing choice, possibly based on a user option. I guess I intuitively think P takes priority since it's specialised for those types?

This isn't something I've solved for myself, but it was making me hesitant to update my fixed-length patches.
