Nobody is advocating for a face-shield as a replacement for an N-95 mask, but using them together, would reduce the odds of infection.

According to the MIT paper, a typical sneeze will travel over 20 feet.

Additionally, there is mention of the velocity of the particles may be able to penetrate the mask, so a face-shield could help with that, too.

Yes. Defense-in-depth. In China, most hospital red zones required 3 layers of PPE, whether that's two masks and a face shield or such. One layer alone is not very good, and a face shield alone is no good. A mask and a face shield are very good, especially for confined spaces like subways and busses where there are jerks coughing and sneezing all over without hygiene or manners.
