No logic works if railway decides to extend to any train to any xyz station.
They will change d name of train they can create more pf washing lines etc..if we search such history we can found so many trains which is extended to xyz station even train was introduced dedicatlly to dt station...nothing matters for railway.
May be u r not agree but this is true.
Even...
more... I wish this train shouldn't be extend becoz the reason u mentioned is valid.
