Good point, but I'm certain the HVAC in 33 is not set up for mitigation and non-symptomatic people in the first few rows could be just as problematic as someone on stage.
All moot, taping at TVC ends shortly and TPTB will have to make a call for the set-up at Haven.
Possibly, but do any of the other shows have hosts that regularly stand right next to the audience? That might be the key - if they stay back a bit from the edge of the stage, they are likely far enough away from most, if not all audience members, and only close to actual guests or the occasional person invited on stage (thinking like Tonight Show with sweaters around Christmas for 12 days).
