I will happily acknowledge all of your criticisms, since I agree with them.
But I'll also point out a big problem with your suggested other questions: employers know that this is a hot-button issue for some prospective employees, and they will adjust their answers accordingly. There is a right answer when a female interviewee asks "Would your previous female reports be happy to work for you again?" - could you imagine anyone answering "No, actually they hate my guts"? And so the only way to get accurate information is to either ask indirect questions, or to ask them to indirect people (eg. finding other women who have worked for this person and asking them what they thought, which is suggested elsewhere in the thread).
Same reason that no sane employer gives interviews that consist of asking "Do you think you're a good employee?", and only slightly better is "Tell me why I should hire you" or "Tell me about your biggest weakness". Sure, you'll get an answer, but it's very likely to be a.) predictable and b.) not highly correlated with how you eventually evaluate their job performance.
