In fact, it always thank to V.
- Panam, without V... probably stay out the the clan and being lost alone in Night City.
- Judy, her life is a long suit of fails/sadness. But I agree, she can leave Night City and have a "better" life.
- Kerry, well... without V, I think he would end "very badly". He was at his wit's end. In french it means that he want to end his "sad life".
- River, it also end well because of V... I think we all know how it end if V don't help him at the end.
To quote Mike P. again : V is not a hero, she can't change the world, but she can help friends, save lifes, make good things around her... So among all the bad things and fails which happen in Night City, thanks to V, some "good things" can happen.
But again, (for me), in the Devil Ending it's all resolved (and I don't use my imagination here^^)
If V choose to go in Mikoshi, it's "clear" it is a dead end... The contract is an absolute lie, engrams don't have any rights, Arasaka don't care about V and already forget her. The same if V return on earth, no one care about V and Goro clearly say that she will die no matter what if she choose this path...
After you can say they talk bullshits, but it's clearly stated. If you return on earth, you know V will die. If you go in Mikoshi, you know it's a lie and a prison...
And the Nomad ending, it's also clear (to me) that "we'll find a cure" from Panam is the same kind of words than when Jackie said in the Konpeki "Don't worry V, we'll manage to get out alive". Clearly some words to reassure yourself... But I agree, It's more subject to interpretation than the Devil ending
Edit : If I had to bet, I'd bet on a sequel that resolves the 2077 endings to begin its own story rather than an ending that resolves everything in that expansion.
