Lol it is ironic that most USB-C hubs focus on providing legacy ports other than extra USB-C ports.
As opposed to the Hyperdrive, which uses 2 ports at USB-3.1 to provide some bandwidth. It might be worth investing in a proper Thunderbolt 3 dock. This will give you full speed over a single cable, but they are more expensive.
Does the display not have any ports (If it's a USB-C one)? One of the main advantages with USB-C is daisy chaining, so you can run multiple things down a single cable. Otherwise could you do with a separate hub? As in the Hyperdrive connects directly to the MBP making it a little finicky, if you got a cabled one and sat it under the desk with permanent things attached it'd be easier to work with maybe.
I've just had a good luck and honestly can't fine any, but I'd be interested too if anyone does find one. I think probably it's because USB-C is basically a multi-port in of itself, and can be converted to any other standard. So they are making breakaway boxes for this. As opposed to simply making pure USB-C hubs.
