I believe the reason for the "blend" was lack of Mobile 1 0w-30 being sold in Canada at the time. Not "out-engineering" anyone. IIRC the goal was finding something similar that lubricates quicker in cold temps.
Yeah a tune/song has been written for mixing a little bit of this with a little bit of that click onto the link below.

Contradiction, yes. If a readily available substitute existed for them. If none was available, you'd want the closest substitute with good properties, as best as you can discern.
I'd recommend using the manufacturer recommendation for your region. If none existed or was easily available, your engine won't blow up using a "blended" 0w-30 instead of 5w-30 for a winter OCI.
People have been pouring any oil off the shelf into their engines for 50-60 years for top off etc, creating "blends", to my knowledge no engine blew up. If your goal is ultimate compliance for warranty, then don't do it. I don't, unless it was out of warranty and I had no choice (stuck on roadside etc, nothing else available). I think the reaction people have here is pretty funny to it however.
