In the pursuit of making sure people are fearful you would encourage using the term "ground glass" when discussing the lungs of an asymptomatic case? Because if you had ground glass in your lungs you would absolutely feel it, and it would feel like ground glass. You would cough and spit blood.

Are they asymptomatic or do they have ground glass in their lungs? It can't be both.

It's not ok to fear monger like that.
