Not only those, but this change will annoy people who prefer to get on a train and just work for the journey without interruptions for changing and degrade service for people with reduced mobility - including but not only those who need to book assistance to board or alight.
Nottingham can be a terrible for changing trains if you have mobility problems or for other reasons need to use the station's lifts (say a family with a buggy or someone with a bike), as they are located at the extreme west end of the station.
If the Liverpool - Nottingham service could terminate in platform 5 and the through Matlock - Norwich services use platform 4 (eastbound) and 6 (westbound), an interchange would be quite easy as they are all on the same island; however, most eastbound services currently seem to use platform 3, so if this continues passengers changing to it from stations west of Sheffield are bound to have a long transfer unless the Liverpool service terminates in platform 1. And if the northbound service starts from the same platform, passengers changing to it from a Norwich - Matlock service are bound to have a long transfer as they would arrive at 4, 6, or 7.
Passengers between Norwich and Chesterfield/Sheffield (and vice versa) will have the option of changing at Derby as an alternative to Nottingham; from experiences, this is a far better station for changing trains if you have mobility problems than is Nottingham (whilst the lift on platform 7 was out of use following the station's fire, it was necessary for a passenger who used a wheelchair and arriving at that platform to be taken off the station from the east end of it, then along the adjacent Queen's Road to the station's west end, then back through the station's main entrance on Carrington Street and through the barrier line to reach a lift to take him/her down to the platform they needed!)
