I think it can play a role actually. As long as the “orange piller” explains custody and whatnot. Success would be the person has some sats in WoS and is eager to learn how to get it into truly their posession, and start stacking, and wanna end the fed, and stuff
Onboarding someone with nostr:npub1hcwcj72tlyk7thtyc8nq763vwrq5p2avnyeyrrlwxrzuvdl7j3usj4h9rq is the wrong way!

But why not start with Breez or Phoenix right from the beginning?
Orange pillers certainly can do that, just a little higher of a step up for the onboard-ee. But i don’t think there’s anything inherently wrong with starting at the easiest point as long as they’re given proper context to want to learn how things really work.
Basically whatever is the best approach is for a given individual in terms of them wanting to learn more is probably the best way
Without wanting to learn there is no orange pill at all
