Have they simply not got around to removing them or do they still play
a role occasionally? Perhaps to let the station staff know when a
train can leave?

Maybe for engineering trains?

I've wondered about this myself, esepcially as neither the Northern nor
Jibilee have wayside signals, save for gap indicators.

IMHO, they simply installed on the Victoria Line a newer and updated
version of the previous system. This mainly starters at stations.

The DTG-R system is completely new and some would say superior to the
Seltrac installed on the other lines (radio, so no wires to get
damaged, better "driving"). As the system uses track circuits, the
colour lights can provide an instant and continuing fallback if the
ATO fails without buggering around with axle-counters. Just a
thought? I'm no expert in it!

According to Wikipedia "LUL claims that this is the world's first
ATO-on-ATO upgrade", which Paris, Barcelona, etc. might have something
to say about.

On the basis that the Victoria Line was the first automatically driven line
and its ATO system has now been replaced? Have Paris or Barcelona done that?
