When I set it up a couple of years ago, it was a hard requirement and looking at their features, it still seems to be the case: https://www.cloudflare.com/plans/#overview (under 'Custom Nameservers')
When I tested a while back, I couldn't setup a subdomain in cloudflare, it only allowed me to setup the root domain. When I did this and just updated the NS records for the subdomain to point to cloudflare, their validation of the nameserver change never passed (since I only set NS records on the subdomain level).
I'm not trying to argue for arguing sake, just trying to show why I thought/said what I originally said :)
Honestly, if this does now work, or there's a way around it, I'll be really happy as I could switch a couple of subdomains to them :D

And, as per (https://support.cloudflare.com/hc/en-us/articles/36001742119... and https://developers.cloudflare.com/dns/zone-setups/partial-se...), they state that 'partial DNS' (i.e. using a CNAME to point to them) is only supported by Business and Enterprise plans.
