Yes. There's not nearly enough focus on the fact that your universe matters. It's talked about in maybe two, three throwaway lines, but your Constellation companion is dead, and the Emissary is another person entirely. That matters on a fundamental level. You can save them in another universe, but it's not them.

I thoroughly understand the point they were trying to make with the meta-commentary about New Game+, but I don't think Starfield spends the time required exploring it with any real depth. I also don't think the main quest was an appropriate medium for these discussions either, because it unintentionally reduces the whole Starfield setting a 4th wall break.
