There are two benefits that come from French bearers when they are indeed buttoned: First, they help to ensure a perfectly flat front for the trousers, and thus also ensure that drape is even. Second, they take the pressure off the single button or hook at the middle point on the waistband. Some trousers may also have a cloth tab which buttons towards the right and provides additional support, again taking stress off the center.
A related point: If the waistband is too tight, there is often a tendency for stress to increase at the top of the zip fastener that is placed on the fly. This can, over time, lead to an unsightly gap at the top of the fly with the cloth of the fly being pulled sideways. The best way to relieve this stress on your trousers is to have the tailor let out the waist to make it fit you better. Most well-made trousers have a couple of inches of fabric tucked into the waistband and seat, and this can come in useful for some judicious expansion!
