Something that I'm surprised they didn't mention: They say that most Italian people would pronounce the schwas by just omitting the last vowel altogether which, if I'm understanding correctly, is the vowel that indicates gender. That itself seems like an appropriate way to communicate "not one gender or the other". It also strikes me as a very believable way for language to evolve.
