That’s a bit sub-optimal regarding how they handle domain setup, I agree. You can get partial functionality by adding a NS record in your existing DNS servers for pointing specific records to their DNS servers even without going through the full domain delegation process. After some testing, we were sufficiently happy with their service to move forward with the full delegation, but this technique worked well for kicking the tires without making the full commitment to their DNS service.
The down side to using the NS trick is that their SSL handling will not be fully active unless you do the whole domain. Depending on what you hope to accomplish, that may be the make-or-break decision for using their service or not. You can still do SSL on the host under some circumstances, but I believe all entries in the top level domain must use their certificates when acceleration is active. Subdomains can still use the SSL certificate on the host even without full delegation.
Another reason to consider letting them handle your DNS (if you can) is that they have some pretty interesting plans for adding DNSSEC support for later this year.
At any rate, what I would suggest you consider is something like this:
test IN NS ns1.ns.cloudflare.com
IN NS ns2.ns.cloudflare.com
and replace ns1 and ns2 with the name servers assigned to your account.
Of course, you need a “test” record created on the CloudFlare end to serve the appropriate DNS entries. This configuration will send all DNS queries for the test host to CloudFlare’s servers and through their acceleration infrastructure.
Hope this helps,
