So to summarize, I think it's technically invalid, but others may well

Most probably. But last time I used Bletchley ticket office, I'm
almost certain I saw an email from ATOC on display (not necessarily
intentionally, but you can see the notice boards from the windows)
that pretty much said that RJIS was showing Waterloo as valid on a
London Terminals ticket via Kenny O, and so that it *was* considered
valid! (And presumably by extension Vauxhall).

Interesting...
