That’s cool! I always forget that internal “devices” are still more than likely hooked up to the USB chip as well, but it makes total sense when laid out like that. Oof, I just aged a decade.

Looking just at the power requirements, I'm wondering how USB hubs without a power adapter ever worked. USB-2 provides 500 milliamps so how do you get four times that much for a four-port adapter?...

I think the answer might be "it didn't work very well?"
It seems like a USB 2 hub powered by a USB-C connector that negotiates more power would be a nice way to go for portability, if you don't want a separate power adapter? Maybe USB-C is more of an addition than a replacement.
I would think the more obvious answer is that there are still millions of devices that use the USB-A plug and it's far more convenient to have it built into your hub than to require an additional...

USB 3 still commonly uses a type A connector, and I believe it predates the C connector entirely (although of course type C connectors also can and do carry the various USB 3 signals). The difference is that USB 2 caps out at 480Mbps whereas USB 3 is between 10x and 40x faster, depending which confusingly-named variant of it you’re using. If you see blue type A ports that’s a signifier that they’re USB 3.
[Edit] The original USB 3.0 standard was released in 2008 and the USB-C connector came in 2014 - bigger gap than I thought!

Most devices back then didn't draw much power from the hub. Anything with even slightly larger draw would have a seperate power supply.
