I think Tolmasky's point was that, even though Web.app embeds the same UIWebView as non-Apple native apps, Web.app was written by Apple. Apple could enable Nitro JIT for Web.app because its native code was written (and audited) by Apple. The only third-party code executed by Web.app is JavaScript that is already assumed to be safe enough to use the Nitro JIT in Mobile Safari.

yes, I think it was.

It makes a heap of assumptions though, and feels kind of like a non-techie person saying "why dont you just whip up a GUI app to trace my IP". Enabling Nitro JIT for UIWebView for some applications without enabling it for every app in the app store is probably more difficult than toggling a switch.
