One thing to note about a thick stack of cloth is that it can be really hard to clean thoroughly. I cloth diaper, and the thicker the diapers the more prone they are to getting ammonia buildup and causing rashes. It's just really hard to get thick cloth clean! My prefolds (which are like a big flat diaper, but already folded into shape and sewn that way) are more likely to get ammonia buildup than the thin "flat" diapers
Some tips to get thick layers of cloth clean (discovered the hard way!):
If the dirt on the cleaning cloth is oil or poop, use HOT water. It won't come out well with cold waterUse LOTS of water. The cloth should really be swirling aorund in the washer really well. So, if the amount you're putting in there would be considered a "small" load, wash it with the medium or medium-high amount of waterHave it churn a long time! My washer's default churning cycle is only 15 minutes. That was not enough to get all the poop and pee out of diapers. So, I prop the door open and keep restarting it so it has at least 45 minutes churning in the waterIf dealing with poop or other biohazards, do an extra wash or rinse cycle on hot.
My normal diaper/nasty rag cleaning goes like this: (1) Wash HOT with medium or medium-high amount of water for 45 minutes. (2) Spin out the water (3) Restart the wash for another HOT wash of low-medium or medium, which my washing machine then completes with a cold rinse.
It's an annoyingly large amount of water, but at least I'm not wasting paper towels or plastic scrubbies!

Now to go look at the article, because I've got a lot of thread-bare, holey diapers I'd love to turn into cleaning rags!
