Coming from a devops background, I kind of wish they didn't support arbitrary docker containers, as I found the experience fairly painful (going through one of their guides), and soured me from using Fly at all. Maybe it was the app's fault, but troubleshooting was not intuitive at all, especially on the networking side.

Unless you're doing something that is explicitly supported with flyctl's automatic setup, I found writing a basic Dockerfile was far far easier than messing with buildpacks.

You'd prefer if they only supported build-packs/nix-packs? I can see the appeal from a simplicity standpoint but supporting containers expands the usecase significantly.
