I don't see an option to enable this in latest iOS Beta Safari (14.5 beta 4). Is this planned ? Without SharedArrayBuffers/Atomics we don't have pthreads in webassembly - so webapps like mine (AvNav) run at half the speed (or less). Please consider enabling it for iOS/iPADOs Safari. Thank you.

I checked latest Safari tech Preview on Big Sur 11.2.3 - No Experimental feature there either.

Was this meant for internal users an testers only then (as the title says)?

And how do I test it? Build Webkit/Safari from Source in Xcode and run my own version on ipAD? Ok, let me try that.

But please consider accelerating the rollout. This has been disable for 3 years now.

Wanted to ask if there's a roadmap / timeline for enabling SharedArrayBuffer by default?
