A lot of these may be perfectly legitimate labels that don't need to be changed.
For example the Norway Turistveger, those may be the same deal as cantch, which doesn't use TCHFoo style labels at TCH intersections, just normal numbered-route labels like MB16.
HRV E751Pul 7(A9) looks fine, as an exit-numbered route. (Ones that don't have "a unique exit numbering system based on its own designation" but are still 100% exit-numbered give me indigestion, but it's fine...)
