Message:

IPC/async: strictly isolate the use of low-level IPC methods (ipc_*) and async framework methods (async_*) in user code, do not allow a mixture of both in a single source file

Benefits for future plans

• The async framework could use different communication style under the hood, but keeping the same high-level API
• The async framework can be integrated more tightly with sessions without potential problems of intermixing session-aware async methods with session-unaware low-level methods in user code
• The async_serialize_start()/_end() can be deprecated more easily
