My money is on the response being "we don't need to change anything but do consider wearing a face covering if you think you might like to and bring a woolly jumper so the windows can be open". 

I bet you're right. I was really cheesed off at some advice about how masks arent needed in tutorials/seminars unless a student is uncomfortable and requests them. That's not exactly encouraging for those very students, when you're putting them in a position of going against the norm. I just want to yell, look at all the people across the university with long Covid, or even 'just' troubling symptoms for a month. Why would you want that?
