What happened to the side track at Highbury & Islington?

Highbury & Islington Overground is going to have a rebuild. The
existing platforms 1 and 2 will become the platforms for the East
London Line, with the North London Line taking the place of the side
track : platform 7 (the "special use" platform) is cordoned off, and
the other side has undergone some severe defoliating recently in
preparation for a new (or reinstatement?) of a platform there.
