Development? The technique has been well known for a long time, I remember hearing about it in the late 90s. It isn't widely used because it isn't practical. Also, your countermeasure doesn't work if there is another reflective surface inside the room.

The difference is that these things used to be the domain of major government agencies rather than a hobbyist with a few hundred dollars and a poor sense of privacy.

In the 70s maybe, but in the late 90s? No, it has been a potential hobby project for a long time now.
