I know I could do that, and that would be great for my personal setup. But I like to run the vanilla versions of popular wallets that I could actually recommend to someone to onboard them to bitcoin/lightning. So I know it’s just going to work. And I also know how *their* interactions with it could run into problems or hiccups.
I had been using Phoenix as my main onboarding wallet for quite a while. The alternatives are fine for me, just because I’m used to using 80% alpha or beta level software and dealing with the pain (and fun) of it all. But I never try to get friends and family onto those tools until they feel as seamless and simple as Phoenix did.
