The immediate suggestion for only one crew member on the flight-deck during cruise would have to consider the content of that ‘operation’ at that time, i.e. during specific flight phases, including the necessity for a pilot to return to the flight-deck.
Also what constitutes ‘material’ times.

AMC 25.1523 Minimum flight crew
1 Both the number and identity of the flight crew members should be established.
2 If the minimum flight crew varies with the kinds of operation to which the aeroplane is limited, the approved number and identity of the flight crew members should be stated for each kind of operation.
3 If a particular flight crew member's station has to be occupied at all material times, this should be stated when specifying the minimum flight crew.

The early versions on the HS125 (Jet Dragon - cf Dragon Rapide) were single pilot, but required a second person with access to the flight-deck to operate the emergency discharge value. Later versions of the aircraft had two crew (but not by requirement), primarily due to longer range flights and to promote a sales image of a grown up aircraft; single pilot during cruise was accepted, a norm.
