I found something on a bread-baking blog (can't find the link right now) that said that you basically have two choices, for the best results:
1) use the flour within 7 hours of grinding
OR
2) age it for 2 weeks.
Flour in the in-between stage isn't going to be quite as workable, or rise quite as well.
Chemistry isn't my strong subject, but what you said about bonds breaking down and rebuilding would seem to fit with that. AFAIK, it's not a nutritional issue, just a question of making "adequate" vs. "world class" bread. But I could be wrong on that point.
The flour used by professional bakers would traditionally be bolted, i.e. sieved to take out the bran and coarse grains. I think this would slow down the spoilage process somewhat, as some of the oils would be removed. They'd also age it in a cool place, not at warm room temperature. Still, I can't see how flour that was aged for a month would be healthy.
