I definitely agree with this

But also I just started a side project with Rails. I got a CI/CD production environment with GitHub Actions, Postgres, Redis, sidekiq, and storage on Fly.io in an hour or two.

The thing that makes me more comfortable here is that none of my application code references Fly.io at all. If the project needs to grow beyond Fly I just change some environment variables and migrate the data.
