Aliasing grim_reaper -> death_(entity).
Reason: There is a distinction made in the wikis, but... it's relatively rare to see a personification of death and recognize it as such without it also being the grim reaper, and I'm not sure the few distinctions warrant separate tagging. Certainly an implication seems to be in order.
(I count about 8 out of 40 that aren't some form of robed skeleton)
...although, perhaps reversing the way the tags currently work would be best? That is, a distinct tag for personifications that aren't the grim reaper.
