I still get the same warning for a multi-device setup (besides some
different address offsets) followed by

    [  196.220085] bcache: bch_open_as_blockdevs() register_cache_set
err insufficient devices
    [  196.259971] bcache (936fcb06-4a1a-4219-a6ff-eca785c178a0): stopped

printed after `sudo mount -t bcache [partition device file]
[mountpoint]` (e.g. `sudo mount -t bcache /dev/sdb7 /mnt/data`) after
creating a bcachefs with `sudo bcache format /dev/sda1 /dev/sdb7`. I
don't get the warning if I format only one device and mount it.

I'm not really sure if that's sufficient for a multi-device setup since
I only found https://bcache.evilpiepirate.org/Bcachefs/ explaining a
single partition setup and there's a difference between commands
explained in `man bcache` and `bcache -h` and `bcache -h` isn't
sufficiently helpful to work with the command.

Are you looking for quite naive end-user testers annoying you about
every minor issue in the documentation and command feedback or isn't
bcachefs ready for that yet?
