The equivalent test for extending a Travelcard, is discovering if any
ToCs don't accept them. I think the answer is "only GatEx are that
petty", but maybe others can confirm.

Careful - I am almost certain that BZ6 tickets are *not* valid on
Virgin trains. I suspect this extends to other IC TOCs as well. It's
to do with different accounting - an outboundary MKC to R1256 is
priced based on the idea that most people will do MKC-EUS on Virgin
then just use the Travelcard around London, whereas in the other
direction it can't work like that because the Travelcard is already
purchased.
