In case it's useful to others, I dropped the size in my compiled binary from 2.4Mi to 2Mi by:
- Not including //src/core:grpc_external_account_credentials (with minor function changes not to try it) - Not including any of the load balancers I was not using (PickFirst is the default) - Removing the grpc_resolver_dns_ares (with a small number of code changes) - Also RegisterFakeResolver, RegisterHttpProxyMapper, FaultInjectionFilterRegister This was done just with an unconditional local patch for now.
