what's coming next is replacing wasmer with wasmtime [1], the runtime closely following wasm and implemented by the same people designing the standard itself.
In any case I wonder what's the need for try to push Wasmer down. Here are your previous comments, all hateful against Wasmer on different announcements:
1. https://news.ycombinator.com/item?id=36128284 (on WASIX launch)
2. https://news.ycombinator.com/item?id=33835683 (on WAI bindings)
Honest question: are you related to the Bytecode Alliance at all? (I saw a comment from you in HN promoting a company from that alliance)
