Each of these services is a complex subsystem requiring its own handshake protocols, encryption standards (often utilizing Sony’s proprietary authentication), and event hooks. Bundling them into a single .bin file suggests a conscious design choice: instead of dozens of smaller dynamically linked libraries (DLLs or PRXs), the developer has aggregated these dependent services into one contiguous block.
