It's not 'wheelchair access', it's 'step-free access'. People with
limited mobility also appreciate knowing they don't have to climb
stairs.

What you say is correct, but that stands for every other station on
the map without the symbol. The two stations are not physically
linked to one another, you have to exit one and cross a road to get to
the other, making it less of an interchange than it appears to be from
the map. If travelling on Oyster, you would have to touch out and
touch in, potentially charging you for two journeys (unless the system
can recognise that?)
