Well, GP proposed removing the idea of trailing newlines from standard *nix tools entirely, so I think it's fair to ask what shop is going to update their RHEL deployment to upgrade to a version of `cat` or `sed` that doesn't have trailing newlines but can't spend 5 minutes to handle a newline properly in their CSV parser? That doesn't make a lot of sense.

And it was pretty clear from the context of norir's comment that they were not talking about legacy software, they were talking about writing new projects/file formats that used newlines as a separator. Just because you want to shoehorn your legacy projects into this discussion doesn't mean that they fit.
