I literally just last month published a beginner guide based on leveling a character without shared stash. I still didn’t touch those columns, because I still can’t see any reason why I ever would. When leveling, it’s not a huge burden to filter to rare+ and just sell trash you can’t use.
Edit: Before the recent loot rebalance, I think it was even assumed that’s how you got your iron bits. After that rebalance, the amount of trash is somewhat less, so while unnecessary it’s also less burdensome.
