I'm sure TFR didn't make it into TSR-2. When Bee did his low level trans-Pennine flight he flew visually, it was a daylight flight after all and I believe he was accompanied by Jimmy Dell in a Lightning T5, so the terrain-following wouldn't have been too severe.
The TFR programme did continue for a while after the demise of the great white beast but it ultimately came to nothing despite having some pioneering display techniques.
