Well, since there is not a lot of evidence of traffic through the
rootwrap, that means almost everyone is using root_helper=sudo. Marking
it deprecated, and recommending that everyone switches to the (untested
yet) rootwrap doesn't sound that much like a great idea.

I think we should deprecate root_helper=sudo when we are confident that
most people are using rootwrap and are satisfied with it.

That sounds reasonable.
