Then they are making sugar honey. Not real honey. The purpose of feeding them it to get the population up ready for making your honey, not to make honey from sugar.

Right, but if there's no flow and you need to feed, why not give them something to fill besides the brood nest?
Once the flow starts, remove the super that they're storing the sugar in and replace with an empty. Then store the frames with the sugar until needed, such as fall feeding.
It seems like a simple enough solution to keep the bees from filling the brood area with sugar therefore giving the queen plenty of room to keep laying.
