I don't think it's a matter of "believing in Lightning".
Paul is a bit skeptical about reliability and has self-custody as a priority, that's why we strongly opposed previous lightning solutions that were custodial.
I respect his point of view.
Edge remains open source, so PRs are very welcome.
Also, you don't need to use shitcoins it you use Edge! Imagine your edge account as a client-side encrypted package where you can collect seed phrases (aka wallets) and maybe in the future ever more things.
You can have Bitcoin-only accounts with as many Bitcoin wallets as you wish.
That's how I use my accounts.
