I'm guessing these changes will also cause a knock on effect to current Nexus services with them having to subsidise (a lot of ) extra services as a result of these proposed changes.
Some of the R routes, 23, 37, 73, 168 515/558 and some Team Valley workers service (whatever is left of them) are ones that spring to mind which could be withdrawn or cut or incorporated into other services.
