...all those problems should be fixed in the toolchains, not in the browser.
Emscripten exists, DWARF debugging support exists and works (I can step from C/C++ code into JS code and back with the WASM DWARF debugging extension for VSCode), other language ecosystems just need to catch up.
You're implying the only solution to unnecessary friction is reams of unnecessary lubricant.
Someone had to spend time building those unnecessary toolchains. Imagine if this time were spent developing cool libraries or use cases for WASM, instead of building out plumbing.
