Ms. did have its own political angle but but when it did finally become mainstream in the late 60s/early 70s, I'm not sure that there were too many people ready to go to the mat for public honorifics that distinguished whether a woman--and only a woman--was married or not. (And at least some people who probably reflexively opposed the change at first, changed their mind later on.)
But honorifics are tricky and some people feel very strongly about them--e.g. Dr. for someone with a PhD.
