Noncustodial Lightning is... a pain. It took me way too long to onboard a noob (Phoenix), and most people simply wouldn't have figured it out. He was shocked that he didn't need to provide any info after installing. I quite enjoyed that too.
I think a tutorial would go a long way in solving some problems with onboarding (explain liquidity, etc). Lightning is pretty complicated when using it in a sovereign way. And annoying at times, to say put it politely.
Frankly, I may not introduce someone using noncustodial again, and that saddens me.
But he has some sats now and is asking questions, so I'd say the experience was a net positive.
