The degraded mounting is a valid concern. Rebooting while in a degraded state is problematic (from a ‘might lose ssh access’ standpoint, not data loss) The other concern seems to be the auto mounting of stale disks, which is by design and works a treat In my experience a much bigger footgun is that btrfs raid makes files with CoW disabled completely unsafe (no sync between disks even when scrubbed), and some distros and programs (systemd-journald) selectively disable CoW by default
