Even with a 2hp pump on high, there would not be enough suction to cause anyone to be stuck to a drain. I also am a maintenance freak, so if a drain cap is broken or something I guarantee no-one will use the pool until I replace it.

I figure on leaving the pump on low almost 24/7... At that I am concerned about proper mixing, thus I figure a single skimmer, two returns across from each other and dual drains about 6 feet apart should give me the best possibility for proper and complete turnover throughout the pool all the time.

I read the entire article and watched the video, and I have little issue with any of that... But, from a "what is ideal" situation where entrapment isn't a concern, I don't see an issue.
I'm also not concerned about entrapment in my pool (no kids btw). The main drain shares a pipe with two skimmers and there's no valve to shut off the skimmers (there is a valve to shut off the main drain). That combined with the main drain cover (checked on a regular bases to ensure its secure) there's simply not enough suction to entrap someone.
