Interesting, I am not sure I would be comfortable at what others would do. The infection rate is higher than at the test match, that would swing it for me personally.
I would also be wary that any infection could end up in our Xmas bubble.
But it looks like I am in the minority on this one, how unusual.
I genuinely would have no issue in going to another game having gone to the friendly.
Entry to the ground was the only real pinch point, but it was a new process for the club, and I'm sure they learned from it - that was what the test was for, after all. Frankly, if you think this could be an issue for you, either get there early or, if there's a queue to get in, hang back until it has cleared.
You don't have to use the concourse facilities, even if they are open, and the seating is very well spaced, even from those you may be attending with!
