I configured BTRFS for my data a couple of years ago on my Debian machine. It's using RAID10 - and the RAID 5/6 issue was widely known back then so I did not dare to touch that.
I must say that (fingers crossed) until now I haven't had any issues with it. There have been a couple of unclean shutdowns that haven't led to any corruptions. Scrub runs every couple of weeks and on top of that the data has an offline (external disk) and off-site (rsync.net through borgbackup) backup. I'm not expecting BTRFS to let me down, but if it does I have recovery options. I tend to be very careful with my 17+ years of photo archives, especially since I'm generating hundreds of megabytes of new content every week since my daughter was born.
It definitely doesn't look good that RAID 5/6 is broken, but I feel very safe using the other stable RAID modes.
Sometimes I'm dreaming of setting up ZFS - however the downside of that is that it doesn't live in the kernel and you're forced to work with kernel modules. It's certainly doable, but since I had a kernel module issue with Wireguard a few months ago I'll be "looking the cat out of the tree" for a bit more before I decide if I actually want to make the move. For now BTRFS feels stable for me, so until that changes - or the benefits of ZFS increase by a fair amount - I'll probably stay on this.
