A quick search turned up two suggestions (1, 2), so it has been suggested. I’ve also voted for both of those previously and will vote for this one too because I really want it, both because sometimes I don’t wanna see some of the models that get uploaded and because I also used to get slam dunked by the workshop downloads too.
I could also see this as being something that could fall under “STREAMER QUICK SETTINGS”. If streamers are playing with a group of friends, they may want to be able to see those people’s models for some wacky antics, while not having to worry about weird TOS-questionable stuff or getting blocked/flashbanged by viewers like xQc was in the Arcade that one time.
