Interesting.
As posted earlier: the films of the Trilogy went through many iterations. It'd be interesting to compare them in a timeline to see how they evolved to the final cut. But the final cut is what counts.
In this case, I'm glad they didn't film the scene above because it would have lengthened the movie without adding to the drama, or improving the Frankie/Roth/Michael/Senate plot.
However, it does deepen the connection between the Rosato brothers and the real-life Gallo brothers (not that it was ever in doubt).
