The plan is to incrementally backport bug fixes and optimizations from
bcache-dev to upstream for the foreseeable future.

As an ethousiastic bcache user myself I would be very happy if there's a
transition plan! :-)

Would it make sense to call this bcache2 and merge both into the linux 
tree once bcache2 is stable enough for broader testing?

To the extent possible, you could reuse common code paths and simplify the 
backporting of bug fixes into the existing stable branch.

Out of curiosity, will the backing device layout in general change, or will
specifically the superblock change? If it's 'only' the superblock (and not
it's size) I can imagine a feasable migration.
