Perhaps we can provide both and default to 3.6? Eventually we will have 
to transition to 3.7, and I think it might be easier if it's widely 
available in oe-core, even if it has known (or unknown) issues and is 
off by default. We can then periodically test 3.7 on the AB etc, to 
assess where things are.
