All broadcast SSI requests, which include WTO, command, and task termination processing, run the entire SSCT chain. Having unused subsystems defined slows down this process. Only directed SSI requests - those sent to a particular named subsystem - use a hash table lookup.
That's true. But, the additional path length is negligible. Only active subsystems that capture SVC 35 will actually get control. A "dummy" subsystem without an SSVT (no INIT routine created one) adds only three additional instructions. One with an SSVT adds just a few more. No big deal. We're not talking about thousands of entries here.
