I don't really mind it when used in the Naruto world, and I would use it for my OCs if I think it would be interesting, or appropriate for them.

I take a lot of inspiration from Chinese and Japanese culture when I try to work around what I try to imagine what Naruto culture would look like; and I like to imagine that across the elemental nations, incest or even marriage between first cousins are accepted to various degree, or not at all so...

Tl;dr: I think is okay, as long as it isn't just used for the shock factor, or like you said, for OCs to have a tragic backstory as a massacre survivor and get the boy at the same time.
