You can. If you set up the modular DAG as I mentioned above, you can now set up service boundaries between the leaves of the DAG. E.g. parts of the code call other parts of the code as a service. You then version and deploy the same codebase separately.

Say you have Libraries A, B, and C, where B and C depend on A and not one another. You can have B call into C via a service, just as you would in a microservice. Now B and C can be versioned and deployed independency. You can also deploy updates to Library A incrementally, tying it to the B and C deployments.
