Definitely people should just wait until they are divorced before starting something with someone new.
I love the law in California - sounds fair to me! If you look at what happens to many women after divorce - many have full custody of the kids and they live at the poverty level because they are refused support, can't afford to fight a long battle using a lawyer, and they can't get the 50% or family assets that they deserve after being in an equal partnership with their spouse over the years they were married. They should do the 50-50 and be done with each other! So many women are at a disadvantage, especially if they have been at home for many years raising the children and need to get back into a well paying job.
