It's a very interesting experience working in a large codebase that's a few years old while we're in the middle of trying to dramatically rearchitect everything because we realized the old way of doing things was creating tons of technical debt and confusing abstraction. Even worse, we're always trying to optimize things because we've got some soft real-time requirements and we're using about 50% of our entire time budget after we upgraded our bare metal servers to Zen4 (it was more like 70% before that). Every fix turns something else into the long pole that needs to be rebuilt with the lessons we've learned about writing clear, concise, high performance code. As it turns out, if you're operating on large data in bulk you should probably just have a dense ID map and then do everything in arrays. Nothing beats arrays :)
