What is the state of the world at the end of the second game?

I was under the impression that we severed the connection between APAS and the 4000 souls, yet that we are still in a Death Stranding world; the Last Stranding still looks and the world is still full of BTs and tar. Yet the epilogue shows an ocean of water, not tar, and the post-game QPid allows you to limit your connection with BTs. What does that mean, canonically? I am also not sure about the implications of the abandoned infrastructure in the epilogue sequence. What is the state of the world after the end of Death Stranding 2?
