Joel Dice of #Fermyon has written a great early look at #webassembly components preview 3 here: https://www.fermyon.com/blog/looking-ahead-to-wasip3.
I very much appreciate the contributor list at the bottom of the post, as it indicates how many people are working toward this, step by step.
I'd also missed ArcJet's Gravity: https://github.com/arcjet/gravity. That's neato, too.
