We recently added a walk through guide for C++ Wasm extension development: https://github.com/istio-ecosystem/wasm-extensions/blob/master/doc/write-a-wasm-extension-with-cpp.md. Before sharing it more broadly, it would be great if we can get some feedback about it internally from folks who do not work on writing Wasm extensions day by day. @douglas-reid @richardwxn It would be really nice if you could please take a look it. Thanks!
