The part that isn't working well enough is faulty status. The drive keeps hanging around producing a lot of errors, instead of getting booted. btrfs replace start ought to still work, but if the faulty drive is fussy it might slow down the rebuild, or even prevent it.
The more conservative approach is to pull the drive. If you've previously tested this hardware setup to tolerate hot swap, you can give that a shot. Otherwise, to avoid instability and additional problems, unmount the file system first. Do the hot swap. Then mount it -o degraded. Then use btrfs replace start.
