It is interesting that this is being touted as having advantages given that it was just a punishment in the past. When I was in elementary school (early 2000s, small town United States, public school) we often had to eat lunch in silence to punish the student body for something.
I have run this casually on my main machine for a few years now. I have a Windows partition, a Linux partition (btrfs on LUKS), and a third btrfs partition where I kept my files.
I don’t use it often, but when I do I don’t even notice it. It’s as if Windows could just natively read btrfs all along. This was without any “advanced” usage beyond simply accessing, modifying, or deleting files.
