Yeah but you need to port the SIMD before shipping anyways?

So if you're doing incremental stuff might as well stub out the calls with "not implemented", and start filling them in.

The SIMD part will be emulated as normal, as far as I understand. So you can ship a first version with all-emulated code, and then incrementally port hotspots to native code, while letting the emulator handle the non-critical parts.

At least in theory, we'll see how it actually pans out in practice.
