[Marvel/DC] Where would some of DC's favorite superheroes stand on the whole registration thing?

Remember how Thor was absent for the Civil War arc? There's a good reason for that.

Superman would be against it, as he would likely see no value in it. If he needs to unmask anybody, he can do it (or use his X-ray vision, drop a few hints, and threaten to do it). If they're too powerful for Superman to unmask, then there is nothing anyone could do if they knew their secret identity. And if Superman is against it, the whole superhero community would back him on it, and that would be the end of the discussion.

Besides Superman, the Justice League already registers heroes quite thoroughly, and Batman has a secret database of everyone's cover identities he can use when he needs it.
