In addition to the security aspect, it would be really great if you have the option to lock down or cache the Docker images used for actions. It was weird for me when I pulled in an action from the marketplace for a workflow, and now about 80% of my total build time is building of that action for each and every build I run (e.g. the Dockerfile is compiled for that action EVERY time I run my build). I should have the option to at least cache that built image for me after the first time I run a workflow.
