Cloudflare folks: do you have plans to support subdomains? I've been using AWS CloudFront and am pretty happy with it, but the performance claims made by CloudFlare were intriguing enough for me to give it a try. I tried adding something like blog.domain.tld, and it failed with: "Please ensure you are providing the root domain and not any subdomains (e.g., example.com, not subdomain.example.com)" Many people would use this service with a subdomain, this is kind of a deal-breaker.
