Oddly enough I constantly run into the same issue on monolithic codebases too.

Things could just be one file but they end up being 12. I had to look through 12 levels of indirection for a single boolean recently. Twice, on two separate projects in the same week.

At least in a single codebase, that issue is at least theoretically solvable. At least the indirection wasn't split across 12 repos!
