I've made goose down duvets. One of the things that gives them warmth is leaving ample room in each compartment for the goose down to fluff up freely. What makes a goose down duvet warm is the ability of the down to trap the warmed air.
If you squish too much down into a compartment or if you make the compartments tiny (such as would happen with most quilting) you will lose the insulating qualities of the down. It won't be able to fluff up properly to keep you warm.
Another problem is washing. The whole reason to have a duvet cover is to protect the fabric and goosedown from skin oils. Each time you have to wash the down, it never quite recovers the amount of loft it had originally, so it is in your own best interests to do whatever you can to minimise the number of washings.
