I think Luffy's awakening doesn't only trigger logia properties but one of his true abilities. What if the resin/oil DF theory is true and Luffy can actually heat, melt and explode his limps without issues since he can re-produce these again?
I always knew Katakuri's logia body might be a hint to Luffy's awakening. I mean, they fought in the mirror world while their abilities reflect with each other but Katakuri's special logia properties do not mean anything in that comparison? I always found that odd - and now we possibly have the answer that Kata's logia body was a hint all along.
