I remember my '57 Chevy had them riveted to the front hubs. Here's a good reason WHY - if your lug nuts come off, the drum stays on the hub even if your wheel comes off. You still have BRAKES for the other 3. If the drum comes off, then you lose all your braking, as there's nothing for the pads to press againest. I'm guessing they couldn't do that with the rears because...it'd be too difficult to engineer properly. I do remember I didnt' like that feature, though, because it was harder to find the correct drum for upgrading an older car. I converted my '57 Chevy to tapered bearings from roller, by cutting the drum rivets off, and using the old drum on the newer '64 Chevy hub with better bearings, which didn't have the drum riveted to it. Worked like a charm. Anyway, not much to contribute here, other than asking whether the drum/hub assembly is actually one cast piece. I'll have to dig some of mine out to look sometime. I remember my '70 Javelin had 1-piece, I "think", with V-8. It's been awhile since I worked on those brakes.
