This is better suited for Site Feedback but just join the existing threads that request for straight flags. The staff didn't make one since they didn't find a suitable design at that time. They plan to release something next update.

Good news! You have the flags.

Thanks for the feedback, though the "we have an ally flag" doesn't promote straight pride. It is for a straight person whom supports the lgbt community, which isnt what I was looking for. I was looking for a straight pride flag/banner.
