I was so pissed a year and a half ago when I realized that none of the hubs had a Thunderbolt pass-through.
The new Anker 7 in 1 has a 'USB-C data' port. Given there's no claim or picture of video out, I'll bet that's all it does.
And the tail on these. It's almost always too short to make it useful to plug it into the back of a thunderbolt display.
I think the Thunderbolt 3 monitor I got recently is my last planned Thunderbolt 3 purchase. I'm not sure if I can hold out long enough for USB-4 to land, where hubs are expected to be hubs again. But barring lost or damaged equipment, I'm going to try.
CalDigit sells a thunderbolt hub that has thunderbolt pass-through, though not if you want to run dual 4K displays @ 60hz (the one thunderbolt port becomes the second DisplayPort).
