Of note - the zones 1&2 and 1-4 Off-peak Day Travelcards are being
withdrawn, leaving just the zones 1-6 Off-peak Day Travelcard extant -

What about the others, like Z1-7, Z1-9+Watford Junction etc?

to promote switching to Oyster and use contactless payment cards

And the extra (on average) pound each time will no doubt come in handy.

Another way to look at this is that some people have got their wish, and
(for off-peak paper travelcards at least) London is now just one zone.

In reality, the Z5-6 aspect was previously free of charge,
