Not me, but some twunt before me in my house. but my house now and I will sort it, one day. maybe.
When we moved into our house, there was a full size door and frame at the back of our cupboard under the stairs, ooh thinks I, Narnia! I open it and do I find a lion? do i fuck, I find myself staring at the contents of one of our kitchen cupboards, and the side of our microwave. The 'door' is an old one, that wasn't removed when the new kitchen was built about 15 years ago.

Light switches.
The switch in our dining room turns the kitchen light on and off.
The switch in the kitchen turns the outside security lights on and off.
The switch in the hallway, next to the kitchen door controls the dining room.

To make matters a bit worse, in our shed (old portacabin), someone has installed sockets AND a fusebox, excellent thinks I, new workshop, Xbox room, escape from the missus place, or all of the above.
Get some bits in there, only to find that the same twunt that done the light switches had installed the electrics in the shed.
The frigging retard had somehow managed to take power from the security lights, so you'd only have power in the shed if the security lights had been activated.
Took nearly a week of wondering why the power kept going in the shed every 10 mins.

I fixed that with a ingenius device, called a bloody-great-long-extension-cord-out-of-the-bog-window, (device name copyrighted), still works a treat to this day.

bloody-great-long-extension-cord-out-the-bog-window
wen we bought our house the old people before hand had drilled a hole in the wall, passed an extension lead out it, hung it 30metres down the garden with taped up connections to the shed. Semmingly similar to your invention, they also used said hung extension lead as a clothes line. maybe you could think of some other uses that could be put to your bloody-great-long-extension-cord-out-of-the-bog-window

other uses for 'insert-excessively-long-name-for-a-long-bit-of-wire-with-sockets-on-the-end'
I did actually hang the claw of my hammer over it about a year ago, it stayed rusting on it next to the shed for about 3 weeks.

Then that bloody sutcliffe took my other one.

excellent
Your "bloody-great-long-extension-cord-out-of-the-bog-window" reminded me of a job I had a while ago where the Powers that Be had banned extension cords on account of them being a fire hazard (sure, if you plug too much stuff into a too-skinny cord, but not if you know what you're doing. Fortunately, though, power strips were allowed, and it turns out that the business community had decided to address our needs by making power strips with 25-foot cords. Win!
