Yes. This is a valid point . I think if you specifically look at trains in East/NE-Kerala sectors especially the GHY group of trains, SHM-TVC/NCJ trains, DBRG-CAPE, one of the biggest complaint was large number of wl passengers/gen ticket holders getting into sl class coaches. Gen coaches in these trains were less. As an additional option they decided to start this. This would serve as a good option especially for those migrant workers who still prefer to travel in general even though the distance is quite huge
