OTOH the words footbridge, escalator or lifts aren't mentioned so
presumably you'll take that as proof they haven't been provided?

Now now. They are the means by which access "via the new concourse"
is provided.

No, they are the means by which only some of the access is provided,
for those passengers who happen to be on the mezzanine catering level.
The main access is through the ground floor alongside the south end of
platform 8. This is why platforms 5-8 have been shortened, to provide
the necessary ground level circulation space.

That's where I'm going wrong - the area you mention is currently part of
the "old concourse" (to be allegedly exit-only), although what they
probably mean is that the exit-only area is the "to be demolished" part
of the old concourse.
