Split the code into multiple files?

[Cyberax]

I know that having everything in one giant .py file makes it easier to distribute the project. But I don't think it can keep scaling, it's already almost 5000 lines long.

I'd love to create more type-safe classes to describe the compose file structure, but that would blow up the code to 10k+ lines.

Perhaps it's time to refactor it into multiple files? With a build step to assemble everything into one blob.
