Yeah, it's pretty stupid honestly. Like you said, it's not as if the models or the atmosphere "listens" to MA weenies and says "oh, they started a thread too early, let's screw them over!!" I can see why SNE might tend to start storm threads earlier simply due to their climatology and they have obviously more leeway in terms of setups for such things. Here, it's kinda silly to start threads really early not due to "superstition", but because we typically are in a more tentative setup and it's better to wait for a bit more information/detail. Otherwise you end up with a bunch of BS commentary going on as things waver back and forth.
ETA: The only times I recall starting threads relatively earlier are for the big events (Feb. 2010, Jan. 2016). But that's because at the time there was such a strong agreement and signal across essentially all models and ensembles, so it made sense.
