Tomatoes, before man got into breading for size were probably the size of a golf ball if that big. Now you can find tomatoes the size of softballs. They taste like c..p but they are big. But are the vines three or four times as big around. No, but you don't sell the vine. Orchids, at least some of them are also being bred for larger and larger flowers but I would bet, though I do not know for sure since I have not been in to orchids very long, you don't see stalk size increasing at the same rate as the flowers. So I would suggest that the staking of the flowers will have to be considered on a individual basis.
