> We don't have the capacity to support Cinder as an independent open-source project

Our team is smaller than you might think! You also left off the last half of that sentence, which is quite important: "nor any desire for it to become an alternative to CPython."

We'd love to see the ideas and implementations in Cinder end up in upstream CPython in some form or another. It'll make our lives easier in that we won't have to maintain as much forked code, and hopefully everyone else will benefit from a faster CPython.
