The USB-C thing is a nightmare because you can’t extend Thunderbolt and every Thunderbolt accessory comes with some arbitrary length someone decided (usually about 20cm) that barely allows you to reorient the device next to the laptop where your hand is supposed to be. There literally exists no male to female thunderbolt extenders in the usb-c form factor. I tried buying a non Intel approved one and hesitantly, after weighing the risks of even plugging it in, found it would power the Thunderbolt device but couldn’t move data. (For the information of the reader, Thunderbolt exists above USB-C and USB-C connectors lack Thunderbolt data pins and hence downgrade Thunderbolt back to just regular USB-C)

The Lenovo 40AC0135US acts as a male to female extender (+ port replicator). I have one on a 6' 40GBPS 100W cable to my laptop, and the 40AC0135US has a female port allowing you to daisy chain X, has been working great the last 18 months with no issues, mac or PC.

  In my case I did something like this (used an ALOGIC part) but glued the extender upside-down under the laptop stand with araldite since there was no easy way of mounting it out the way of my hands but close enough that the 15cm cable would reach. Voided quite a few warranties working around the awkwardness

This is by design. It is a unbelievably high-bandwidth interface. It has strict physical limitations and it is expensive to create products that are capable of pushing those limits, thus the 16" passive cable limitation in many affordable devices.This is all kind of annoying but enables creation of devices that were not possible before, and what on earth any of this has to do with USB-C which is an entirely different signal pathway without these particular limitations is anybody's guess. (Mostly what I cannot suffer is the fools who position these limited passive connections on the wrong damn side of the device.)
