But does it benefit from a usable platform?

There are stub platforms, perhaps 4m long, on each line. If a train (in
either direction) stopped at the old starter signal as if it was
stopping at the station, you can enter the driver's cab from the stub
platform.

During WW2 (and perhaps still?) it was possible for someone waiting on
the stub platform to manually replace the signal to red, in order to
"hail" a passing train.
