GitHub actions isn't going to run your Python code on its orchestration infra. Nor is DigitalOcean or Fly.io or CircleCI. They all convened around "YAML" because it's a very limited set of instructions.
I'm quite sure you cannot write a bitcoin miner (or something that opens a backdoor) in Liquid inside YAML in the DSL that Github Actions has. I am 100% sure you can write a bitcoin miner in Python, Javascript, Lua, or any programming language that Github would use to replace their YAML config.
What? GitHub Actions, at the very least, isn't strictly yaml. I run arbitrary code in whatever language I want all the time. I'm pretty sure third party workflows can, too.
