I've had an iPhone for years. I didn't even know albums existed. I've just noticed the tab in Photos when I went looking for it after reading your comment. And it turns out, I do have one other album already, with a couple of photos in it, though I have no idea why or whether I created the album or how the photos got there or what purpose it serves.
When it comes to security features, simple and obvious behaviour is good, pretty much always. The same is true of user interface design, and the lack of both documentation and natural discoverability on iOS has always been a pretty glaring weakness of the platform. Complexity creates edge cases, and edge cases create vulnerabilities, including due to misunderstandings and resulting human error.
Judging by the other replies to the parent comment, apparently I'm not alone here, so I'm guessing if Apple did any user research about this, that "big debate" probably lasted a few seconds...
