So, you write code that already runs natively (previous compilation process) to run it throught a kind of virtual machine so it can run natively. Nothing more to say.
It has some cross-platform quality to it, like you can run the same C++ program in Windows and iOS without recompiling it (like in Java times). Not sure about performance though.
IMO the main target to develop code that must be compiled to run is to improve performance. Java, ES6+ or any other uncompiled code don't reaches great terms of peformance against compiled ones. The target of uncompiled is "develop one, run everywhere".
To sum up: taking a code which main target is perfomance, transpile it to a cross-platform version (loosing performance throug the process) and then execute it everywhere using a VM ... it sounds, kind of ankward for me.
Thats a very good question. The biggest advantage is portability. Think in this way you need a language specific runtime to run your code. What if you have a single runtime that runs all your code (irrespective of multiple languages).
Java, ES6+ or any other uncompiled code don't reaches great terms of performance
Do you mean JavaScript here? Yeah with WASI you have a runtime the gives you a better performance than JS (NodeJS) alternative.
You will not use that level of performance. But yes, if you just want to write C++, WASI is not an option.

We're a place where coders share, stay up-to-date and grow their careers.
