Has the behaviour of the uri rule been changed at some point to match the whole of the URL? I have just noticed I am getting some FP when one of my uri rules matches against the URL rather than URI. To prevent FP would be very difficult, I think to match the whole of the URL with uri rules is not such a good thing, if you wanted to match something in a URL it would be quite easy to do so in a body rule but to match just against URI isn't so easy.
