Fortunately, it held.
As I circled the K model whilst troubleshooting (no green light and told by ground folk that R main was dangling) I read something interesting (something I probably should have known before it truly mattered):
With that particular model if there's no positive indication of the nose gear being locked (only one light for all three) then suspect that the engine may be holding the pressure in the line to support the nose. During landing roll and taxi do not allow revs to drop below 1000 until a locked indication is given or (from the AFM) "ground crew" have secured the tail to the ground to support the weight. I got the green on touchdown so no pilots sitting on the tailplane/tying it to the ground that day.
In reference to my last post this may have been why the pilot elected to not secure the engine... depends on the model, the info she/he had at the time etc.
