Yes, it was very much tongue in cheek. It's the idea that they think the former East juniors clubs destroyed the grade by leaving for the senior EoS league yet their alternative plan now is to move to the senior WoS league. The West juniors moved to a senior league; the only difference being that they all moved at once (other than Dunipace who moved earlier). Whatever happens, if they move then they will be leaving a junior league for a senior league just like Kelty etc. did.
I don't think they need to change the name. Some teams will drop the junior aspect, some will keep it for historical reasons.
