Are store-bought rabbit hutches big enough for a rabbit?

The recurring message across r/Rabbits and r/Bunnies discussions we read is that even larger commercial hutches are often too small on their own. Community consensus is to use a hutch as a secure base for sleeping, hiding and a litter box, then attach an x-pen or provide several hours of free-roam time daily. If your rabbit will be confined most of the day, size up well beyond the minimum or build out a connected pen.
