A lot (not that I clicked all that many) of these are suggestive + full nudity, which I think is reasonably E.

I see them as non-suggestive + full nudity which would be softcore and Q. What makes them suggestive to you? They are just nudes either standing, lying, or sitting without doing anything sexual. You would group those images with the real hardcore images with sex, rape, ect happening?

I think if vaginas are the dominant bodily feature in an image, like a big arrow pointing and going "this, here, is the purpose of the image"--then it's also reasonably E.

I disagree, since they are not doing anything sexual, like penetration or masturbation.

This is the main reason I would propose a new rating instead. Personally I am not very fond of hardcore images, and prefer the non-explicit (hint hint) full nude softcore (think artistic nudes) sort of like the ones I linked. There is no way to currently separate these images, even though they are of two totally different extremes.

Here is wiki's definition, but not necessarily the one we have to use (they didn't have a discrete entry for artistic nudes, which is a bit tamer but usually falls under the softcore umbrella):
