No it will be the same level of skill and difficulty to do correct shared memory multithreaded programming. You'll have to manually manage locks and reason about potential for deadlock or other race conditions. If anything it will be harder as the implicit serialization of the GIL being removed means libraries might suddenly develop race conditions that you've never experienced or seen before, likely causing spectacular crashes and undefined behavior or bugs.
