Discussions, post-mortems, analysis, inflated egos, and all that jazz.

That is, I know a billion times more and better about both Heroes and music.

As a person who knows firsthand what a diminished fifth and a cadential quartsext are, and who can also distinguish moderato from mordent, I would like to note that most of the "creativity" of Kurt Cobain, in terms of music (from a professional terminology point of view), has only an indirect and mediated relationship.
And the analogy with Kurt Cobain is also not correct, just like the analogy with Mikhailovsky Mozart - both are absurd.
However, this is essentially a different game. Just as different as the version of Warlords was at the time.
If we talk about musical analogies: Hota is more like variations on a theme. Likewise, any other unofficial version is a variation on a theme.
It's just that the "composer is dead," and all that remains is to either listen to the original or listen to variations (or try to write your own variations). And from there, it's a personal choice for everyone.
So far, variations come and go, but the original lives on. What will happen next, time will tell and everything will fall into place.
