As a Fedora user I would like to throw my 2 cents in from my personal experience and say I
support this proposal.
I've used btrfs on a home NAS since Fedora 25 (now running F32) without any issues.
The ability to resize the filesystem and change RAID levels has been super beneficial but
the ability to detect bit rot was really the deciding factor especially when storing
valuable files like family photos.
In addition to the home NAS I also run btrfs on my laptops and desktops without any
noticeable performance impact compared to ext4 and XFS. The ability to take snapshots has
been really nice to recover from the accidental mishap like deleting the wrong file.
