Optimize template RPC return types
Summary
[Migrated from this GitHub issue.]
Despite the first templated RPC migration, not all RPC method return types have been optimized. Currently, only a very reduced subset of the RPC methods are being used. However, this number is destined to grow.
What is the expected correct behavior?
Each time an RPC method is used for the first time, its return type should be checked and revised to see if it matches the expectations. If not, it must be updated.
