It probably could help yes, especially if you're looking to just not partake in that kind of content, if you're in an unwell state say... but then again it's nice when you don't label yourself. When you're just free to make anything; there's no distinction you need to follow; no specific intention with you art; just free expression entirely...
Could maybe have warning cues/categorization in titles too if you want to let people avoid specific things. Or use tags for the same purpose. Though you don't see either of those if you get to the art directly via the user page of course, hmm...

Sounds like and interesting idea, but this definitely needs time to see what will happen.

True. For now, I believe said idea is probably best only in theory. But I hope things work out.
