It's a short-term pain, which will eventually go away.

Can't we start by shadowing the ipv?.dns-* options into a generic dns.* option set so that they're identical? We can give people a long time to start using the new location, before eventually taking away the old ones.

We definitely shouldn't be making the problem *worse* by doing things like the ~ prefix hack or adding any *more* fields to ipv?.dns-*. Can't we at least add that as dns.lookup-domain even if it's all by itself in the "DNS" settings for now?
