He mentions induction 'hot plates' towards the end, and says that they're limited to the same 1800W and 120V as kettles, but there are "commercial" portable induction stoves that are 220V and can go up to 3500 and 5000W; e.g.:

Just need a NEMA 6 plug (GFCI/AFCI per code as well probably):

Sure, but over in 230V-land 3500W hot plates are completely standard, and can plug into any regular wall socket. Same with microwaves and hot-air ovens: just put it anywhere on your kitchen countertop and plug it into the nearest socket.

We do also have a "kitchen plug" for high-powered appliances. Those go up to 7.3kW in their regular dual-single-phase 16A version, 11kW when wired with three phases (quite common in households these days), or even 17kW with the (understandably) rarely-used 25A plug variant with three-phase wiring.

And that's not even commercial equipment, just what you'd pick up at your local Best Buy equivalent. The commercial stuff uses CeeForm, which is a three-phase 16A/32A/63A/125A plug. Or it's getting hard-wired.

What is the specific standard for domestic 16 A and 25 A 3-phase plugs you’re referring to?

Not OP but - I can't answer the specific regs, but 16A/240V is absolutely bog standard for the UK and every high street store stocks ovens that will draw this down. They need to be on their own circuit, e.g. this [0].

I've never seen a single oven pull more than this, but devices like [1] are fairly common where you have two independent ovens in one, and it can pull 21A - this would necessitate the 25A supply.

As for three phase - https://www.howdens.com/-/media/howdens/assets/clh_asset_pro... this hob (which I have) will take 3-phase 16A, or single phase 32A. I've not come across any 32A 3-phase devices for home usage, though.
