What you can't do without them is DNSSEC. The DNSTSIG (transaction signatures) is flawed in a number of ways, including that it has a small replay window built into it, and it relies on certificates all the way to the root, and it has been made clear that this will not happen so long as the algorithms are on patent and/or can't be exported.
