In enterprise systems, it’s always easier (organizationally) to add a feature than to subtract one. Subtraction usually puts some work in the queue of some team, which is usually not politically viable.
For instance, say Team A is used to receiving a report in Excel every week. If an upstream system is added or changed, Team A will fight like hell to keep their Excel report even if it’s no longer needed. Whereas “the system shall generate a weekly Excel report” is just another feature in the backlog and much easier to sell to the organization.
