In addition to what others mentioned, typically EDNS0 edns-client-subnet is truncated before forwarding.
For example in unbound the defaults, when EDNS0 is enabled (disabled by default), are:
max-client-subnet-ipv6: 56
max-client-subnet-ipv4: 24
Forwarding can also be conditionally enabled for specific clients, upstream servers, specific zones, etc.
