Not really.
It makes the railway more expensive to operate because more traincrew need more route knowledge.
The connections might fall on the wrong hour for people to find useful.
It would lead either to uneven pathing between Norwich, Ipswich, and Cambridge and Ely.
That would be at the cost of reliability and capacity at Ely Station, not to mention longer journey times.
yes more expensive, but revenue would be enhanced as direct journeys more attractive than changing
yes some connections worse, but connections irrelevant on the many new journeys that can be made with no changes
yes uneven pathing a pain, but that is inevitable, today frequencies, stopping patterns and spacing of services far from regular/even on many Anglia routes
yes some reliability and capacity cost, but capacity released by running fewer longer trains, and some small time cost (Norwich trains have a minimum 4 mins at Ely to reverse in any event) to current direct journeys, balanced by much shorter journey times where a change is no longer required
dont get me wrong, i get it is not a priority, but it is a route where my sense is franchise maps and entrenched service patterns have led to a service that is sub-optimal from a passenger user-friendliness and overall aggregate revenue generation perspective. There is after all, other than historic accident, no reason why Stansted and Cambridge should have services to Birmingham but not Notts/Sheffield/Manchester/Liverpool, and Norwich the reverse, while Ipswich and Bury (together have almost as much footfall as Norwich) dont have any services beyond Peterborough at all
