I'm not convinced. I genuinely don't think the sanitised "safe standing" would be anything like the old days.
It wasn't just about standing up. It was all about the togetherness and those amazing big swells and surges in the crowd, none of which to the best of my knowledge ever killed anyone.
Having everyone standing up in neatly penned off rows is not the same thing. For me that's just standing up for the sake of standing up.
