Using Client Subnet in DNS Requests

Can these ECS records be used to make load-balancing decisions that aren't based on topology?
I was thinking of using this for a delegation subzone between F5-DNS and Infoblox in which all traffic would hit Infoblox and then get delegated to F5 via CNAME. If traffic to F5 is only being sent from the same Infoblox Device, I want to do active/active and get different results based on the client that sends the original DNS query and thought that ECS might be able to accomplish this, but haven't been able to setup correctly so far. I see the ECS entry send from Infoblox to F5 but it doesn't seem to affect load-balancing decision so far.
