For #2, OWC puts a screw hole above their dock's thunderbolt ports so that you can attach a stabilizer around the cord

It's a poor imitation of old ports that had screws on the cables, but should help reduce inadvertent port stress.

The screw only works with limited devices (ie not the Mac Studio end of the cord) but it can also be adhesive mounted.

That screw hole is just the regular locking USB-C variant, is it not?

See for example:

Looks like it! Thanks for pointing this out, I had no idea it was a standard.

Apparently since 2016 https://www.usb.org/sites/default/files/documents/usb_type-c...

So for any permanent Thunderbolt GPU setups, they should really be using this type of cable

Note that the locking connector OWC uses is a standard, not the standard. This is USB we're dealing with, so they made it messy: the spec defines two different mutually-incompatible locking mechanisms.

Of course they do.

Now that’s one way to enforce not inserting a USB upside-down.
