Maybe. Senior RFs ko shayad idea ho uska.
Janta, Antyodaya, Jansadharan are all unreserved category, Humsafar have a different fare structure, same as Garib Rath, so they can be considered as category of trains like Rajdhani, Shatabdi, Intercity etc.
But somehow I feel Kaviguru, Vivek and Karmabhoomi are no longer category.. they have same SF type of everything, say it coach Composition, fare etc.
Ganga Sutlej is known as Kisan express, not this train
