A transactional key-value store *is* coming. That's my end goal in
this: a standardised transactional key-value store built into the C++
language with bindings for C, Python, .NET and so on. I'm currently
hoping to bring that for Boost review start of 2017 (anyone who wants
to bring it to Boost by next spring instead can sponsor me for a very
reasonable hourly rate, drop me a line if you're interested).

I did a bit of mocking up of what the refactored data_store interface
for that AFIO tutorial will look like:

Ok, so it's no longer the world's simplest key-value store API and I
deliberately dropped the STL iostreams interop, but the big
difference is that this one is real-world ready and probably quite
close to a final API design for such a thing.
