The Spin operator is moving towards supporting a components field to enable running a subset of components of an app: spinkube/spin-operator#323

This plugin should support configuring it:

spin kube scaffold --from bacongobbler/hello-rust:latest --component "hello" --component "world" | kubectl apply -f -

Ideally the plugin would also validate the components selected (exist and do not break service chaining), but that would require adding support to pull the OCI artifact, which could come at a later stage.
