The book heavily recommends doing it. That's probably why people think it's an integral part. Also the character creation process assumes you're doing it. It's presented as optional only so much as the book says "hey you're thinking about skipping the funnel? You should really do it."Gotta second this. I was playing DCC for a couple of years before I even knew the funnel existed. At some point it seems to be seen as this requirement, but its a total optional game mode.
And I can see why if you're sold on DCC, funnel is great, it gives everyone a great origin story for the party (IMO if you keep it to one session, but a lot of the funnel adventures will probably be more than one session). But if you're trying to sell the system to your friends... Level 3 pregen one-shot
