So is it safe to use btrfs for a basic Raid-1 yet?

  Yeah, the non-parity RAID modes have been safe for a pretty long time, as long as you RTFM when something goes wrong instead of assuming the recovery procedures match what you'd expect coming from a background of traditional RAID or how ZFS does it. I've been using RAID-1 (with RAID1c3 for metadata since that feature became available) on a NAS for over a decade now without loss of data despite loss of more drives over the years than the array started out with.
