I must get someone to show me this supposed step-free route to the
Piccadilly Line at King's Cross.

Northern ticket hall, lift down to new passageways; short lift down to
platforms. (The only access that's not finished yet is the lift down
from the old concourse to the Northern Line platforms)

The current access to the Northern ticket hall from King's Cross main
line is not step-free.

There are five that I can think of (are you saying some are out of
action temporarily). Working around the complex clockwise:

There's a lift just inside the St Pancras extension that goes up to the
Kent platforms and down to the passageway to the NTH. There's another
lift by the stairs which come out near the KX Suburban platforms. The
third lift is by the stairs that give access to the KX mainlaine
concourse near the large departure board, and the fourth is out by the
main road and leads down to the old concourse, which is then a level
passageway all the way to the NTH. The fifth lift is inside the western
ticket hall and gives access from road level to the barrier level, which
connected by a level passage to the old KX tube concourse.

All but the first mentioned are on this diagram I did a year ago, from
various plans, before it all opened ...

(the numbers refer to the kind of lift, not an ordering that they are
currently using on the signage - which doesn't include my first lift
because it appears to be regarded as a St Pancras mainline lift not a
tube station lift):

The only lift from ground level only goes relevantly to the old tube
concourse which does not have step-free access to the Piccadilly Line.

That's the fourth one in my list above, top half of lift "D".
