Firefox invented and is still leading development of wasm. And Safari is really only distantly related to Chrome these days, their last common ancestor was in 2013. Wasm wasn't even announced until 2015. Safari's JavaScriptCore replaced the JS JIT in 2016, and V8 has had two new compiler pipelines since then.
