I must have misremembered, they did say they're moving away from nomad in https://fly.io/blog/a-foolish-consistency/

edit: And here they say they're replacing nomad with their own thing: https://fly.io/jobs/platform-engineering/

The new thing is `flyd`. I'm writing a blog post about it, right after I write a blog post about our inscrutable hiring process.

We would sooner all eat a bug.
