I also have no relationship to RH other than as a user of their free stuff.
Yes when it became apparent that BTRFS was not ready RH did that. It was a slight surprise when it happened if I remember correctly.
I said RHEL v9 OR 10. I guess 9 is unlikely but 10 is a number of years off. If BTFS is a sucess on Fedora and stable then they will surely consider it. That is the point of Fedora...
