Will E* remove AWS equipment as well as third rail contact gear at
some point?

It's interesting that the trains will continue to require separate
British, French and Belgian safety systems solely to approach the
respective termini (and French classic lines for certain sets of
course). Plenty of complexity there to add to running costs - I
wonder how quickly E* will remove the shoe gear...
