What you say above resonates with me Thierry, I think this is a gray area,
and I think we have a TC to provide well informed value judgments for
this gray area while we seek to bring the dark and light sides closer
together so there are fewer shades of gray to judge.
For what it's worth, I think Poppy is perhaps soundly in the very middle
of the gray area. There's nothing about it that smells like a poorly
behaved free rider grab for free development resources, nor does it feel
like a lock-in attempt. It legitimately feels like something that
enables OpenStack users to consume services that sit outside of OpenStack.
So, for me, the users are served by this project developing closely with
OpenStack, even if there's no viable free way to consume it. I think
Neutron tap danced through this gray area early on, and now has reached
a point where it is clearly in the light side of things, with _multiple_
free drivers that are completely viable. So, let's let Poppy tap dance,
and let's keep making sure our TC is well informed and makes thought
out decisions like this one, even if they are hard.
