I am not entirely sure what kind of radio fuckery happens, but my phone (Oneplus 6 with LineageOS) can be connected to a 5 Ghz wifi network and have a 5 GHz hotspot open at the same time.
I am assuming the wifi chip has two (or more) somewhat independent frontends, since my home wifi and the phone hotspot are on two different 5 GHz frequencies.

Well, technically that’s not a “hotspot”. ¯\_(ツ)_/¯ it’s a Wi-Fi extender.

And a poor Wi-Fi extender as well, since you halve your network bandwidth by using an extender with a single radio chip.

I’ve only seen that option on phones with two radios, it uses the 2.4GHz radio for one connection and the 5GHz radio for the other

That’s kinda required. I doubt one antenna can simultaneously send and receive.
Anyway, there’s still only one controller, so your bandwidth is still halved.

I’ll have to disagree on that one, WiFi extenders extend an existing network, keeping the same network and DHCP is done by the original access point.
A hotspot creates a new network, and DHCP is handled by the hotspot, not the network on the WAN side.
