The thing that gets me about Jesus' admonitions against divorce following the Beatitudes, is that he's talking about a heavenly ideal. It's not just "do not steal" it's "do not covet", don't even look at a woman in "that way", a marriage is to be based on complete harmony, love and trust forever, not merely a social contract. Those ideals are pretty much humanly impossible, which I think was the point. A marriage broken down by disharmony, anger, violence, hatred, or mistrust is already a failure. The divorce is merely the confirming paperwork.
I think the WTS's handling of a "scriptural divorce" condemns couples to live in a damaged relationship so far from the heavenly ideal as to be an abomination. Free them already.
