The bulk update request #9837 is pending approval.

create alias exposed_ribcage (87) -> exposed_rib_cage (0)
create implication exposed_rib_cage (0) -> exposed_bone (673)
create implication exposed_skull (91) -> exposed_bone (673)
create implication exposed_skull (91) -> skull (22872)
create implication exposed_bone (673) -> bone (37339)

Reason: Exposed bones are still bones. Ribcage has already been aliased to rib cage so the exposed variant should keep that pattern.
