This is impressive, but also seems to fly in the face of their raison d'etre. I don't even bother with k8s on AWS because it's too complex for even a mid-size operation. Isn't the point of PaaS to obscure complexity?
We're not replacing Fly.io and the Fly Machines API and the Fly Launch stuff in `flyctl` with FKS. FKS is just there for people who want a K8s interface. If you're not interested in K8s at all, you shouldn't touch FKS.
Most of these PaaS are just abstracting their k8s away from you in the end anyway. But they'd never tell you that, they need to be able to switch back to Mesos or whatever the market heads to in 10 years without scaring customers.
