I have found a blog post here which gives more detail:

"Full extent of the works at Liverpool Central is:

* Improved larger staff accommodation at the back of the station
* Installation of a new lift adjacent to the current lift at Liverpool
* Central
* Replace escalators
* Relocate plant room to free up platform space
* Install platform edge gates

That's an extraordinary one, as it will require precise stopping by
the driver to get the carriage doors to align with the gates!

Gates are normally only deployed on automated systems, where the train
is brought to a stand by electronics. *Is this an early indication
that the new Merseyrail stock will have automated control?

I was under the imperssion the Jubilee Line Extension was run by
conventional driver-driving-the-train technology rather than something
more computerised, and they line up with the platform edge doors (that
seem to have a lot of tollerance in terms of the ratio of platform
door width to train door width).

IIRC the Jubilee Line has now switched over to an automatic system.
It was conventional for a long time despite the original intention
that it should be automatic.

OTOH it utilizes different technology than the Victoria Line.
