It's not that it's "bad", it's just SDK2 was a lot easier and simpler to learn, so much so that the average brainlet could do it. SDK3 is way more advanced and more aimed at coders, programmers, and also sorts of advanced minigame Udon shit. Most brainlet SDK2 mapmakers didn't want to bother relearning literally everything and have it be 10x as complex as before.
