We absolutely have not moved to K8s. We've just added a feature that lets you run K8s, in a particularly simple configuration, if K8s is what you want. If you weren't already interested in using K8s, you shouldn't touch FKS.
The ordinary way someone would boot up an app on Fly.io is to visit a directory in their filesystem with a Rails or Django or Express app or something, or a Dockerfile, and just type `flyctl launch`. No K8s will be involved in any way. You have to go out of your way to get K8s on Fly.io. :)
