It's similar to the Part 135 passenger IFR/autopilot SIC issue, although dealing with the aircraft's certification rather than the type of operation?
Correct. Basically the FAA is spring-loaded to require two pilots on turbojets, but if all the conditions are met, you can operate single-pilot on some of them. But that provision does not prevent normal two-pilot operations if conditions warrant, or if desired by the pilots.
