How ready is this?

I'm thinking about doing some dynamic workflow generation and it would sure be nice to use a format like this Format2. But looking at your tests I don't see any with multiple steps in a single workflow, only nested workflows and subworkflows. What do dependencies between steps look like?

Start by reviewing the existing tests for nested workflows and subworkflows, then inspect how Format2 currently represents workflow steps. Determine whether multiple steps and their dependencies are already supported or need a defined format. Done should include a clear dependency representation and tests covering a workflow with multiple dependent steps.
