FAA has recognized that "complexity" is not a simple as flaps. controllable prop, and retractable gear. Now a pilot needs no experience of any of those to have the aeronautical experience to be eligible for a commercial single engine airplane rating.
I doubt that anyone could be completely familiar with the capabilities and traps of a TAA in the required 10 hours. Lack of familiarity with a TAA can bite you as hard, or much harder, than mistakes with gear or prop.
