Inferior duplicates?

Earlier today an anon uploaded quite a few Crade pictures to the website. The only thing is, they were the censored versions.
 
The artist noticed this and actually uploaded the uncensored versions himself. The thing is however, we now have essentially duplicates of the same picture (around 20 or so) one censored and one not. What do you all think? Do we keep all the pics?
 
I’m not for just deleting artwork, but I do consider them duplicates. What do you think? It would also be nice to get the artist’s opinion as well.
 
This was actually a question an anon had. (nsfw link)

I agree, to a point. I’ve never agreed with the stance of keeping objectively inferior (such as censored in addition to censored, unless the censorship enhances or significantly changes the image) or otherwise unnecessary duplicates (such as alt. formats when one format is legitimately universally supported). This includes prior versions of “corrected” images, such as keeping >>501754 (nsfw, foalcon) in addition to >>527634 (nsfw, foalcon). However, when an artist explicitly desires to have these alternates, that should be honored.
 
That said, a distinction would need to be made: Where is the line drawn on “inferior”? What about sketches and sketch progress compared to the complete work? How do SFW vs. NSFW alternates differ in this regard when the differences sometimes amount to a single line or curve? And how is censored vs. uncensored significantly different from low-effort edits in terms of inferiority? Just some additional considerations.

I agree that if the artist wants the images to stay then that would be the end of the discussion, however, he didn’t upload the censored versions and specifically uploaded the non-censored ones.

@acres  
I got that. I was just making an explicit point that both versions should remain if an artist actually wants both versions to remain.

@Azure Fang  
Okay well then let’s leave the whole inferior thing to the side and bring up the point of the images being well pointless. Why have two sets of barely different pics? Some of them are only different by one solitary black bar.

@acres  
The same could be asked about NSFW edits of SFW images (and visa versa) in some cases, where the difference between N/SFW is literally a quarter-inch, vertical line, such as >>1782042 (sfw) versus >>1939582 (nsfw lol) or >>2092903 (nsfw) versus >>2679946 (suggestive but iunno why). My counter question is, what harm is there (besides server space) in keeping censored versions? The existence of the censored version may be pointless to you, but to the artist it may actually be important.
 
EDIT: And then, as a hypothetical situation (not to mention one that happens in every fandom), what would happen if a third-party were to de-censor a censored picture? Which would take precedence? The censored version is clearly the original, but now we have an uncensored version.
