What does that comment accomplish?

I'll bet if some power cord manufacturer came up with a high end twist lock with matching outlets they would get some attention. Not sure how they would address the female end at the component though.

Hubbell manufactures exactly what you describe, and since it's already UL approved the expense of having it certified is already taken care of.

I use the cryo version in my own system to accommodate 240 Volt for Euro gear. It's a great sounding combo and works with 125V and 240V up to 30 amp.

Here's the male at Amazon rather than the Porter Port version. Hubbell twist lock

I too use tie wraps to support cables but I use them on everything. RCA, XLR, AC cables and anything else that might cause stress on the device it's plugged into.
