This is still true, but to a matter of degree. Even in the feature flagged deploys mixed with canary the permutations are all evident, and ideally tested. Also

This is still true, but to a matter of degree. Even in the feature flagged deploys mixed with canary the permutations are all evident, and ideally tested. Also, you wouldn’t expect a schema change to occur with code that requires it. Those will need to happen earlier. Real systems are complex. A monorepo is one attempt at capping the complexity to known permutations. For smaller teams, it might collapse to a single one.
