Yeah, it shows that I have zero knowledge about commercial appliances. I guess, I wouldn't be surprised if they routinely use 20A plugs / receptacles. Would make sense. Maybe, hospital equipment, too?
You would routinely see IEC sockets in use in Europe in commercial kitchens, factories, anything outdoors like a music festival etc. Partly it's for higher power appliances (including 3 phase power), but also the waterproofing.
They're also the socket found in datacentres (in Europe) to connect a UPS or PDU.
Home users see them at campsites, marinas, and for charging electric cars without a special car charger.
