Yes, the BSSV can basically do anything that you can write using Java. Since Java has many libs that expose integration options easily (email, HTTP/HTTPS, etc.) , the BSSV can be a good way to add that to a JDE ecosystem. Writing those integrations at an O/S level (BSFN) can be more difficult, and are also obviously platform specific. For example, we developed a generic BSSV to monitor an email account and process the messages. We also created several BSSVs that consume REST APIs for item master integration. Yes, orchestrator is being pushed as the standard, but BSSVs still have their own advantages.
