On Artistic Nudity

Considering a lot of pools have been getting converted into tags lately, I was wondering about the logistics of doing the same with pool #2709 (Artistic Nude), as of all the various pools that could be converted to a tag, this is the one I feel should be a tag for people to search for.

However, I worry about the possible overlap of pool #1536 (Casual Nudity), as both handle a similar concept of "Non-sexual Nudity", which probably should face the same fate. What ought to be done here?

I feel like having these two as a tag is a bit subjective, as the only thing that separate casual nudity from zenra is how the setting treated nudity. So I think for now they should stay as a pool until there's a definitive answer to that question.
