for people, NLR might be a preference I agree, but fo railways in operations perspective, GDR is more feasible as the TT will be designed such a way for most trains that it will have enough slack at GDR..so adding a 2-3min scheduled halt (instead unscheduled which happens most of the time for one or the other reason)..
but yea, if they give any one of them also,purpose will be solved
