Yes, but of course the only thing that matters is whether or not the car can do it. That it requires hardware and software is important to techies but a non-issue to regular drivers. They buy cars, not 'hardware and software'.

And if by some chance it turns out that more hardware was required after all they'll try to shoehorn the functionality into the available package. If only to save some $ but also not to look bad from a PR point of view. That that compromises safety is a given, you can't know today what exactly it will take to produce this feature until you've done so and there is a fair chance that it will in fact require more sensors, a faster CPU, more memory or a special purpose co-processor.
