> Using a full-featured RPC framework for IPC seems like overkill when the processes run on the same machine. However, if your project anyway exposes RPCs for public APIs or would benefit from a schema-based serialisation layer it makes sense to use only one tool that combines these—also for IPC.
It might make sense. Usually, if you're using IPC, you need it to be as fast as possible and there are several solutions that are much faster.
