Dellacroce, Answering your question.
DiFronzo is viewed upon as a living legend who retired from the street rackets. He is still a Boss, but not an active Boss of anything with the street rackets.

It would be the way I would view Paul McCartney. He will always be a Beatle, he could step in and try to do the Beatles thing again with Ringo and John Lennon's kid and George Harrison's kid, but he WILL NEVER DO IT.

That is the way DiFronzo is viewed in the Mafia World.
