The bulk update request #6022 is active.

remove implication severed_head (1192) -> decapitation (2121)

Reason: Decapitation is "the act of removing the head by force, usually by cutting" while severed_head is "a head that has been removed from the rest of the body."

A severed head does not always need to depict the act that led to its removal; e.g., a severed head on the ground.
This issue was mentioned in the original implication thread, but nothing came of it.

In cases that feature a body without a head, use headless or missing_head instead.

EDIT: The bulk update request #6022 (forum #383899) has been approved by @slyroon.

Should the implication go the other way instead?
Decapitation -> Severed head
Maybe also
Mounted trophy -> Severed head

Also suggested in the last thread, not a good idea.
Decapitation does not always show the head in frame. In severe cases, the head can also be completely obliterated (e.g., shot_in_head) or bitten off (e.g., Bite of '87)

Maybe also
Mounted trophy -> Severed head

I raised the issue on another thread, saying it sounded vague and to use trophy_head instead.
Mounted trophy heads could also be potentially disembodied_head or detachable_head.
