It's not that we should change to be like other sports - it's that Open has never meant what you think/feel it does (in the context of sporting events)
It's untrue to say that it's never meant that, because it did mean that in MPO for as long as I've known or cared about disc golf tournaments.
Ironically you mention Nate Perkins in this as an example. He was in the room when the vote passed and was part of the standing ovation thrilled about it.
Sadly unsurprising that Nate Perkins was part of the crowd eager to poop in Weema's breakfast cereal. That's a pretty solid argument against the rule change, in my opinion.
