Wearing a mask, even poorly will reduce the chances of spreading a respiratory virus. Is that reduction meaningful? That's a really hard question to answer in any sort of binary way. Combined with how bad humans are at processing/understanding probabilities, you will never have wide consensus. As for the specialists, antidotally, I've never heard a medical doctor claim anything other than a mask is helpful and they all seemed to wear theirs quite happily.
