Yes, and this is just an extension. Existing WASM compiler front-ends for non-GC languages don't have to necessarily use it. Wasm itself still won't take a performance hit, unless individual devs opt in by using front-ends for GC languages.
I mean, you can keep playing this game and take Microsoft ActiveX or Google NaCl as another spiritual successor. I maintain that WASM has been around for 3 years.
And WASM has been around since 2017, which is only 4 years, not 10 years... Bitcoin has been around much longer (~12 years), for example.
