At first sight, it might seem the situation is just like a high-wind landing on an airfield, but there is a difference: on an airfield, if you line up for, say, a 3-degree approach, but the wind is stronger than you anticipated, you will need more power, it will take longer, and your descent rate will be reduced, but your flightpath will be as planned, with that 3-degree slope. In the case of a ship moving away from you, not only will you need more power than anticipated, but the path you follow will be shallower than planned, as it ends further away than anticipated.
There were two practice approaches, so the mobile-landing element may not have been as significant as you're suggesting. That's of course hard to say either way.
The lack of communications means that the pilot could not be warned of the specific difficulties and dangers of landing on a moving aircraft carrier, over and above the ordinary difficulties of a short-field landing of the sort every pilot is supposed to be proficient in. In that circumstance, my guess is that minimizing the novel dangers would be the way to go, but, as you say, we are all just guessing here.
