I have. LoC was in the millions. Half a dozen languages too for the different parts of thw monolith. Worked on by a team that peaked at 100 or so. Multi hour build times too. SVN too! Monolith is still better in my view, despite having experienced that. The key IMO is to have a clear and singular vision and how all the different parts need to fit into it. If you let each little clump of people do their own thing, then you will have chaos.
