I'll add that many engineering organizations also began to drop the idea of full stack development as they grow and split up into independent, semi-autonomous teams. When you have 300 engineers writing code into one monolithic code base, a lot of the advantages of a monolith become major liabilities. You can throw a lot of process and tooling at it, but eventually it slows you down enough to the point where splitting things apart makes far more sense.
