Tangential, but curious how did you get to 100k lines of TF? I’d imagine most things within your company would follow very similar patterns and therefor be extracted into modules, and the per app/team code would be relatively small and focused on how to compose these modules together.
Modules are useful only up-to a point. Creating complex modules with a ton of moving parts makes it difficult to make changes, to upgrade etc. The best recipe that I’ve found is to use modules to enhance some core functional component and then compose these modules to build infrastructure, rather than defining your entire stack in a single module.
