Reason: Getting the amputated_* tags to make implications back up to the main amputation tag.

On a related note I wasn't sure if portal_amputation should imply amputation since, despite the name, they're quite different in appeal.

No to keeping amputated_* as a whole, for reasons mentioned on topic #42665.

Also no to portal_amputation implying amputation, for reasons mentioned on topic #41480.
Amputation refers to "removal of a limb by trauma, medical illness, or surgery" and portal_amputation is none of that.
