That sounds sensible and underappreciated indeed.
2WAY is concerned with what happens once data reaches the node and multiple parties can affect the same state. Shared state needs rules that are explicit and applied the same way everywhere, otherwise different nodes will reach different conclusions over time. In 2WAY those rules are enforced by the system itself rather than reconstructed by applications. It sounds like Reticulum can move data very well, but does not aim to define or enforce shared history, which is the problem 2WAY is built to solve.
