Turbo would be great for PSX runs as well, the only reason I understand why it isn't allowed in non-JP is because that's what the rules have been. I do not think that is a good reason. It's really just as simple as creating a new category, which I can't imagine being that difficult. This is the main leaderboard for the Final Fantasy series now, and I think each category should have representation for times.
I would agree that there would have to be a community consensus as to what to allow on the leaderboard, and I see that the support for that just is not there yet. However, I don't see the harm in having the option for those categories to be there for people who choose to run that category.
Just because it's banned by default in Western communities, doesn't make it a bad idea to adopt for certain categories. Even more so with games where mashing takes up a large part of the game play. Doesn't make sense and restricts people who may want to start speedrunning this game.
I'd have to disagree with this change. Playing this game without the Roses and Wine mod in my opinion makes the game unplayable. However, I do agree there should be a level field when competing for a top time. I think a fair compromise would be to add the time time that could be gained to the final time, but from what I understand that time is negligible at best.
What is in place as of now makes me not want to even learn the game, and I think it is a bad idea. Another idea would be to simply separate the categories if adding the time would be too arduous of a task.
