The email acts as an identifier. And you want that if you want civilised conversations in your site. The email is used by K2's Akismet integration and is checked for validity when a comment is submitted.
There is no plan to remove it as such.
Additionally, it serves a purpose. The email field may not be publicly visible but it's there for custom plugins to utilize it, e.g. for new comment notifications.
There's always the option to just use a 3rd party comments extension or something like Disqus or Facebook Comments.
