Yes of course they have like sparkocam or manycam and of course the mentioned below v4l devices on linux
Nobody has created some sort of fake virtual camera thing? Like it appears in device manager as a real webcam, but the output is altered?

I’d assume that this is something that can be most-easily bypassed at the browser level if a site can request access to a camera.
I dunno about Windows, but at an OS level, Linux can do virtual video-4-linux devices, which is probably how the OS exposes a camera to a browser on Linux.
