Fedora 42 installer defaults to btrfs? What's everyone's opinion or experience on that? (slrpnk.net)

Not a tech support question, I'm just curious. I recently installed it. Everything is working great, feels like I got a whole new laptop compared to my previous setup. I haven't tried out any of btrfs's unique features, so I dunno, nothing special I can report about it. Coming from Debian I was just surprized by how different Fedoras installer defaults are. Do you agree with btrfs being a default option?

I'm talking about the implementation of RAID5/6 for BTRFS specifically.

The RAID56 feature provides striping and parity over several devices, same as the traditional RAID5/6. There are some implementation and design deficiencies that make it unreliable for some corner cases and the feature should not be used in production, only for evaluation or testing. The power failure safety for metadata with RAID56 is not 100%.

BTRFS documentation

Do you know if the documentation is outdated? Has this changed recently?
