2 MLOC is insane. I assume some of that might be test code and other infrastructure, and it's basically impossible to compare apples to apples in terms of code size. But for reference, 2 MLOC is around the same code size as PostgreSQL, which is also a complex distributed system, has arguably a lot more user-exposed features and a long history, and is written in C of all things.
