Sanji is not a Supernova, but he is a member of the Worst Generation, as are the SH and the crews of BB, Law, Kid, etc.
No, And no.
There is nothing unoffical about a supernova, Either you are part of it or not.
Same with the worst generation. it was clear in the manga that the worstgeneration are the 11 supernovas + black beard
Yet again nothing unofficial about it. Sanji is simply neither by definition
