The real question is why did the UK decide that on the outlet itself is the best place for that switch, as opposed to e.g. in the US where outlets are sometimes wired to a switch located next to the door to the room?
Switches located next to the door are for lighting, as opposed to switches on the socket which mean you can fully turn off your rice cooker without unplugging it. We do sometimes have sockets in the UK with the switch at the door, but they are usually a different shape socket that is designed for a lower current and is only intended to be used for floor lamps.
The specific-plugs-for-lamps think is very rare these days. The reason for it is that it’s not uncommon for our plugs to be on a high amperage circuit - sometimes 30A, occasionally higher - that can’t be safely controlled with a light switch or similar, so the lamp-only circuit will be capped at, say, 3A with unusual plugs to avoid someone trying to connect a tumble dryer.
Having a switch next to the door would be useful if you’re using that socket for a lamp but not if you’re using them for anything else. In my kitchen the sockets for my under counter oven and fridge are under the counter and the switches are above it so I can easily access them.

That is specifically what switched outlets in north America are intended to be used for.
So you don’t get confused which outlet the switch turns off.
