Power over Ethernet (PoE) basics and beyond

What about PoE for 10G Ethernet? I see that there are some vendors (e.g. Ubiquity) that are offering devices with it, but I don't see it in the standards?

I think every major vendor has had 10G PoE switches: Arista, Aruba/HPE/Juniper, Cisco, Extreme, and Fortinet for sure. The problem is there is little use case for 10G + PoE in the enterprise and even less for consumers. Ubiquity likes to tout it for the 10G APs... but, realistically, most are worried about airtime with APs, not 10G wired throughput from a single one when they have a thousand.

As a result, it tends to be relegated to the "high end switch which has every feature those one-off customers demand but costs an arm and a leg as a result" model/family. E.g. the only ones I ever sold were to a hospital that wanted to have select switches have 10G for radiology workstations but also wanted to still be able to plug 1G APs in without having to think about the port types. Radiology was covering the cost, so they didn't care it was a waste of money.
