One potential argument in favor of expecting large-particle transmission is, “Colds make people cough and sneeze. Isn’t it likely that the most common infection that causes coughs and sneezes would also be one that spreads easily via coughs and sneezes?”
But I’m not sure how much evidence that really provides. I’m curious what others think.
I would think diseases adapt via an evolutionary like process. If people who display visible symptoms spend less time interacting with others (stay home from school, don’t go to parties, take sick leave), then there’s selective pressure to have less symptoms. Either those symptoms aid in transmission, or there isn’t any standing variation in coughing / sneezing severity which seems unlikely.
