Restoration of the Shoreditch - Liverpool Street connection, providing
platform capacity at Liverpool Street (Crossrail could do that),

Neither the connection nor the platform capacity is the issue. The
problem with Liverpool Street is that the 6 approach tracks are at
capacity in the peaks.

OK, the approach capacity not the platform capacity. Crossrail could
still solve it.

As for the connection, it could be a problem depending on how they
construct the ELL-NLL link.
