It's more an issue of either having an uneven depth after loading the bin, especially if the farmers are storing it all winter to sell the next summer. To do this you need to closely monitor the temperature and use the ventilation fans to bring the grain down in temp gradually to prevent spoiling. In order for that ventilation fans to do their job well the grain has to be a consistent depth.
Virtually all systems will produce uneven depth as the bins are loaded. You usually either end up with an upward cone in the middle from the pile, or an inverted cone when you're using a bin spreader to distribute the grain around the bin. The other time you can have an issue is if you have a powered spreader and forget to turn it on and load the bin unevenly on one side, which could end up being a structural issue.
