I disagree strongly on this point.
Interoperability is one of the cornerstones of OpenStack. We've had
panels about it at summits. Designing an API which is not
interoperable is not "a fair tradeoff" for performance - it's
destructive to the health of the project. Where other projects have
already done that, it's unfortunate, but let's not plan to make it
A lack of interoperability not only prevents users from migrating
between clouds or running against multiple clouds concurrently, it
hurts application developers who want to build on top of OpenStack
because their applications become tied to specific *implementations*
Just my 2c,
