"That device is formatted with a special marker, and its leading blocks are hidden when accessing the device by way of bcache."

This would mean that I can't add ssd bcache to existing device/filesystem, right? Would be nice to be able to add and remove bcache when needed for a existing dev/fs.

I believe if you've formatted your device ones for bcache you can still always add/remove a cache device. In other words, it should run just fine without any cache device.
