[spoilers for Thor Ragnarok and minor Love and Thunder spoiler ahead]
The climax of Thor: Ragnarok sees a giant monster plunge a sword into a planet, causing its destruction. This movie was released a few months after WOW patch 7.3 came out, where we see a planet-sized celestial plunge a sword into Azeroth, permanetly changing the landscape.
The end of Thor: Love and Thunder sees a character being welcomed into the afterlife. Seems pretty clear they intend to explore this plane of existance in the future; not unlike WOW shadowlands which is approaching 2 years old.
I sense a pattern, here.
