I feel like if you have the capacity to analyze the character arcs on a deeper, more philosophical level than your average layman, you'd be able to derive a fair bit of value and honestly even enjoyment from the epilogues! Yes it is messy and if you have characters you're attached to it WILL probably hurt at several points, but I think the epilogues have a LOT to say about when its time to let a character go, what happens if we demand more and more from a story in perpetuity? What happens to people in a world where relevance, in the cosmic sense, can only be perpetuated by dialing your base traits up to 11? is that a world worth living in? What happens when these traumatized, messy characters finally have time to sit around and try and move on from it? can you move on from it when by definition your trauma is what has sustained life as you know it?
The epilogues and HS^2 Beyond canon can hurt and can suck, they can feel cruel, but it's kind of to be expected! people themselves are messy and hard to be around sometimes and that's no different in these stories! As narrative works that explore the concept of self, characterization, and what it means to grow up? That shit is FANTASTIC work, all around, and a fascinating deconstruction of what happens to a story on the fringes of canonicity,
