It kinda is. The local configuration data _overrides_ the resolver
trying to find the answer. By wanting to use CNAMEs, you want to
invoke the resolver to find answers.

You can CNAMEs in local data pointing to other local data? That really
begins to look like authoritative name server code. Other software that
combines an authoritative server and recursive server (eg bind) might
support that but unbound is not an authoritative server.
