That's true, to do that they use a different hack and we can actually (very expensively) route those too.

These tickets are valid only on a particular service (and connections), since the franchises run the services they can sell tickets for services they run.

Example from a journey I made near Xmas:

  0908 from Bingley to Leeds (Northern Rail)

  0945 from Leeds to Kings Cross (LNER)

  1309 from Waterloo towards home (SWR)

The three franchises get 100% of their part of these routes, and I'm notionally forbidden from, say, getting on an XC to zigzag South and avoid London altogether instead.
