Even than if it worked, I would find these kind of miners with usb-c highly dangerous. People, who doesn't know much about electricity or doesn't make some research in this topic can easily burn their homes down only by plugging a usb-c miner in a hub and letting it behind running without any super active cooling. 
They would/could think, it's a small n cute, noiseless device - which it is -, compared to a 1000W+ asic miner, so what wrong could possibly happen?! Well... The thing is, in my opinion, that people are broadly used to using fastchargable and other devices, what support 20-60-120W input capacity. They, in most cases, only see the number and think the bigger, the better and don't even know, what it in fact means. It's a hell of a load. Maybe I'm wrong and way too precautious but even 12-15W is enough dangerous, if you don't know how to handle it.
With usb-a miners, though, there can be theoretically no problem regarding heat. I mean, you can cool them down with a fan or two and don't need any uber extra knowledge. However, if you want to use usb-a miners on high frequency (aka high amperage) and run them on max, you must do some research beforehand, in order to accumulate a level of understanding what's going on in the background. Otherwise, you're stuck with the idle, "safe" frequency, or with older usb miners, which are safe to use and almost PnP devices compared to a compac F.
If someone want to mine for a living won't buy any low hashrate, unefficient usb miner and additionally geather the pieces they need to get them work, but a robust 1000W+ asic. For hobby miners and DIY fans should a usb-a compac F or something similar be enough to play around with.
It's rather about fun, possibility of solving a block in this case, than being profit driven. I'm not saying usb-c would be a dead end or would be bad, I only find it risky and a bit too dangerous. That's why I reckon usb-a miners are enough. Who knows what kind of super-chips the future and the developer misterminds bring us.
