I think it's a safe guess that such an emulation would be made correctness-first.

But most apps are not very parallelized, only computationally heavy ones are. Those are of course going to suffer from emulation anyway. As a performance lower bound we can imagine that it would emulate a single-core x86 so the memory model differences wouldn't come into play.

Microsoft already has x86 emulation working in Windows for ARM, anyone know implementation details of that, or even publications?

It seems to depend on a feature that is specific for Qualcomm processors: https://news.ycombinator.com/item?id=14318877
