Even something like masks has so much disagreement amongst the scientific community.
Pros:
Reduces droplet transmission into the environment
Protects the user from inhaling large droplets and obtaining a more dangerous high viral load
Is known to reduce R0 when worn by the community on a widespread level
Cons:
Depletes PPE supplies for health workers and encourages dangerous stockpiling
Promotes a sense of complacency and makes people less likely to abide by social distancing measures
Protection is not full proof and is very inadequate if masks are worn incorrectly which, for the general public, they almost always are. Fomite tranmission can actually be more likely due to improper mask usage.
Do the pros outweigh the cons or vice versa? Well the experts in the field have not reached a consensus on this point. And I suspect this is far from the only thing where a consensus has not been reached.
