Right now, the query order for DNS servers can vary based on query times. Using DNS from multiple providers is great to prevent outages, however, it isn't as helpful when mixing/matching DNS queries where some DNS providers utilize domain blacklisting. Case in point, it would be great to use Quad9 for primary and secondary DNS and only use Cloudflare if there is a problem with Quad9. This could be performed by either artificially slowing the DNS for Cloudflare to ensure it is always 3rd or by creating an "only use in case of failure" option for Cloudflare if the primary/secondary DNS are both down.
