For languages like C++, Rust, Swift, or really anything targeting LLVM/supported by LLDB, I strongly believe that going with the GDB remote protocol is the best and easiest way to support debugging, but I also totally acknowledge that the trade-offs may be different for Wasmtime. That said, they also don't necessarily need to be mutually exclusive.

I agree that the GDB remote protocol is the best / easiest way to debug everything supported by LLVM / that isn't interpreted in some way. Regarding the interpreted languages, I'd say that there is also a use for this king of debugging for allowing runtime developers to debug their runtime when compiled to Wasm. Most issues in an interpreted code that are not Wasm-related can be debugged on the language's runtime directly without going through Wasm, and Wasm-related bugs will often need access to the runtime as the bug being Wasm-specific may have something to do with the runtime.
