It's funny because people discard The Homestuck Epilogues as "non-canon" while they are SO FRONTALLY more relevant, sincere and brutal of a sequel than, like 90% of sequels.

They go right for the throat.

To me, Meat and Candy are equally important, true and intense. That's the way I read the double novel in 2019. When finishing it I understood the proposition as:

"This story entirely REFUSES to hierarchize its realities and more largely the various and contradictory incarnations of a diegesis, it's the ultimate gift to the fandom because it nukes the very idea of an official canon as superior, while at the same time giving us a bold, powerful follow-up to the events."

It's also worth saying that The Homestuck Epilogues NEVER define themselves as "non-canon" or "post-canon". They are specifically described as "Tales of dubious authenticity". It expresses a doubt, not a certitude of non-canonicity. And I'm joining Lupa's voice in saying that in the end, said doubt is an illusion, and a tool used to pushed the ideas further.
