Apple says they are working with Microsoft and Google to meet all FIDO standards on this. It's still early days, but FIDO as a standards body does seem to be working towards standards for working with heterogenous keychains. Given how many users use Chrome on Windows and have an iOS device, I think heterogenous keychains are going to be critical to mass adoption and everyone says they are working towards that. A lot of this may be on FIDO to truly coordinate.
