iso6400 is not a panacea, its gain added at a large amount and you only have so much headroom.

You don't have to set iso 6400. You can "underexpose" lower iso in order to protect the highlight headroom and then apply the gain in post.

Exactly, I just said the same below, that's exactly what you would do, well most normal people will try and stick below iso1000 and pull it back in raw in post.

Yes but doing this linearly there is no different than using higher iso in the first place. If you push iso 800 linearly 3 stops you have iso 6400 noise wise. So in a sense you need in the first place a camera that will respond well to severe underexposure which is the other name of high iso :).
