Can't see this being a hit with muslim women.
There are plenty of Muslim women who do not do a full-face covering - the vast majority, I suspect. I don't think a simple head scarf is going to interfere with facial recognition.
People who follow one orthodoxy or another (religious, political, ethical...) will abstain from aspects of secular society that are incompatible with their beliefs. An Orthodox Jew wouldn't use an electronic device of any sort on the Sabbath (How dare Apple make an iPhone that can't be used on the Sabbath!). And let's not forget those groups who consider photography/portraiture of any sort to be forbidden - this is clearly incompatible.
When cultural clashes of this sort occur, it's up to businesses to decide whether they accommodate a particular religious group, or not, and up to the individual to decide whether using the product is compatible with their beliefs. It's little different than any other feature - some people insist that Apple convert to open systems. Good luck with that!
While I can understand that people would prefer that a new, un-released product be everything they dream, no company is under an obligation to accommodate every one of those dreams. In the end, as with any other product on the market, the consumer can compare products, and buy or not buy as they see fit.
