Everywhere. Normally adding an extra endpoint to the REST API would take a sprint. Now PM expects you to do two. Only way to get that done is a lot of vibe-coding and delivering sub-par results.
Of course they do. Generally the end result from this is bad - reduced in scope, buggy, and/or unstable. But that's an issue with communication/expectations/management. It'll keep happening either because of politics or the fact that a sub-par deliverable still meets the needs of the overall organization. Until it doesn't.
