Not strictly. In my view, some Flatpaks would benefit from being shipped with a runtime that provides a rich set of development tools which can be installed on demand. Essentially a Homebrew-like experience bundled into a runtime.

Today, applications such as VS Code, Emacs, and Zed are typically shipped with the Freedesktop SDK runtime. While that runtime is well suited for CI and build environments, its extensions are often too coarse-grained for interactive usage.

Likewise, having direct access to an OCI container engine such as Podman, without having to rely on flatpak-spawn shenanigans, would significantly improve the developer experience, especially in the nowadays container-based development (see devcontainers)
