For an example, my team owns a dozen services and they have hundreds of direct and transient dependencies. Of those, maybe a dozen or two to need work to support the new version but that's a dozen different teams that have to put the work on their roadmap and prioritize it. When the entitlement is 'devs want to use shiny feature X with hard to quantify productivity benefit' it's difficult to prioritize. When there's an efficiency benefit then things move fast because a 10% efficiency improvement means 10% lower server costs and that's easy math.
