The entertainment industry, specifically touring rock shows, use the 3-ph + gnd version to power chain motor distro. It's a rugged connector, handles 50A, and is cheaper and smaller than a pin-and-sleeve connector of roughly comparable stats.
The blades are shrouded too, so it cuts down on bent pins from being smacked around in road boxes too.

For sure and this applies to any usage of 50 amp cords.
If you are handling 50' to 100' of 8/4 or 6/4 rubber cords you will drop them and handle them roughly. Standard twist lock pins will get bent, no maybe about it.
These California 50s take a beating no problem at all.

They take a beating but still get beat. I've replaced enough plugs that were so out-of-round they wouldn't mate. Does take some special work to achieve this-
SceneryDriver- I've got a couple of (well marked) 3-ph CS motor tails in the kit. With single-phase motors becoming more common, don't use them much. (The 1/4 ton motors are almost cute.)

You are assuming that both ends of a portable cord are Cali-twist.
Not an option if one end of the cord is hard wired.

Sorry, no, that is not the result of normal handling; that's from abuse- either badly whacking them around while stringing, which needs un-mated connectors, or from driving over them. It takes a lot of work to bend that metal, I couldn't even flex the shell with 18" long Channel-locks (didn't have a vice handy).

Handling that's likely to damage connectors is, IMNSHO, abuse. As they say, "We don't do that 'round here." (My "'round here" for this is temporary event power- we don't have the time during setup to deal with broken parts, so we try not to break them at all.)
I'm curious what industry would call that kind of damage "normal".

You're right. Yup.

There are several standards to which things are built, in increasing levels of robustness:
1) Residential
2) Commercial
3) Industrial
4) Military Grade
5) Nuclear Weapons Proof
6) Stagehand resistant

Those little 1/4T and 1/8T motors are adorable. Fischer-Price's My-First-Motor line. They come with the optional "Bubble Blowing Lawn Mower" kit during the holidays
