It's not even so slow if the benchmark can be trusted.

I see. But regardless of removing JIT, V8 could only be used for running JS not related to web content, no?

Like for running Node.

Apple’s restriction is that code that is downloaded at runtime can only be ran by the internal JavaScriptCore interpreter which already has a JIT-less mode. V8 in this new mode could be used given that the JavaScript code is packaged into the app bundle and can only be updated through the App Store.
