In my observation, when opposite-sex dating occurs between coworkers in all but the largest enterprises where contact cannot be avoided after a breakup, one or the other employee will end up leaving -- usually the person with lower status or value. Even if they tie the knot, you may find one or the other partner wanting to work "somewhere else."
As a manager, you should be prepared for this eventuality once you become aware of the activity. It is unreasonable to forbid all dating since many happy marriages were established between people who met in the workplace. It is reasonable to let people know that they may face dismissal if their dating issues enter the workplace and prove a distraction for themselves or others.
On a practical level managers wish to avoid unnecessary turnover or drama in the workplace. Knowing that employee dating will almost inevitably lead to one or both of these things, I understand the "frown upon" aspect. The employees themselves should be adult enough to know that they are gambling with their jobs.
