We should find the middle ground where the immunocompromised die and the reactionaries still bitch about it. /s

From my limited experience with a person that worked in a hospital it often is also logistics and practicability, as well as the "personal touch". To change masks regularly means you need stations for them, which is extra work that takes from the stuff you are already doing away a bit. It also means that you are less likely to get sick and others are less likely to get sick (except if Masks contain problematic substances and you are working with them for 40 years). Then people don't read your face so well when you wear masks, which is true for regular OP masks, too, and you have problems with glasses. But FFP2 masks and better ought to become standards now that the price for them fell by a factor of ten in medical context.
