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.
I am amazed that anyone ever needed a "sprint" to "add an endpoint".
It usually speaks to the approach you are taking, but I also believe sprint-based planning leads development teams to make work fit into it instead of needing natural time to do it.
Let's remember that all of have probably built full systems over a weekend. What organizational dysfunction has led to us needing a sprint is what needs fixing.
