To be very honest I never knew connecting journeys on different TOC could be claimed via delay repay system.
I take your point about auto delay repay, but I am stopping off in Manchester, then getting a day single to Leeds, so there is flexibility, if my first leg is late.
As an aside going on the Settle to Carlisle train, which I have wanted to do for years.
Return from Newcastle, I left large gap in Manchester, just in case I missed my timed connection there as I didn't know the first TOC would be liable!
