WASM is slower than running JavaScript on V8 in almost all scenarios and will likely continue to be for a very long time. Also, many of us don’t want a compile step.

No, wasm has higher performance and lower memory usage. Here are two practical, real world examples:

While I don't want any compile step either (js should stay), I'm actually confused by your statement.. are there any benchmarks? Are you saying that for example v86 would run faster without wasm?

[nephy]

I think that would probably fall outside the norm. My information might be outdated, but I was under the impression that JavaScript usually wins in most algorithm benchmarks because the JIT is so good.

That is a misconception; there is a cost of abstraction, although this cost may disappear if AI gets really smart.
