That won't cause implementations to be fixed. The implementations in question are in devices that are old (DNS is over 40 years old) and will never be upgraded. Affected users will just choose a different DNS resolver. Pretty soon word will get around that "if you don't want a broken device, don't use CloudFlare for DNS". It's less hassle for CloudFlare to just maintain the existing de-facto standard.
