It does, if there's structural gluten to support it. Bread generally has much more than pound cake.
And in the case of bread (and not pound cake) there is that component of oven spring coming from yeast, which, in a hot oven, dies quickly. Paula Peck (and later James Beard) pushed for decades a low-labor Cuban bread recipe that had essentially no proofing time other than the period in which the oven warmed, after the bread was put into it cold.

Except you eventually reach a point where the structure of the dough is established, the gluten is form and the dough more dry -- think hardened cement. Longer baking time won't make much difference at that point (which arrives at a different time with each case) except for dehydration and browning.

In part, yes. Apart from the tendency of fats, dairy solids, and sugars to aid in browning, the egg yolks, sugar and butter in pound cake all act to reduce the role of gluten in the oven spring.
Adamantius (who may have lunch in the Brooklyn restaurant with the alleged best claim to the birthplace of the deep-fried Twinkie, and loath to omit mentioning Twinkies in a post when given the chance -- what would Mario Nebbits say?)
