Alias 'Head' to 'Bust'?

head -> bust
 
I wouldn’t have thought so at first, but looking through the head tag, it looks like it’s been getting used either in addition to or in place of bust. In the cases where it isn’t, those images seem like they’d be more accurately described with disembodied head.

I’ve tried to clean up head for the most part in the past. I still need to do another review of it before any such aliasing. I might alias it to “head only” and imply bust from that once it’s all cleaned up.
