Why would there be a 'consequent change to the entire operation of the
system'?

It's would be quite feasible to operate in auto mode as far as the last
station on the segregated stretch, have a driver board, and switch to
manual for the remainder of the journey.

I was thinking more in terms of reliability. The current automation
means that the speed of every train can be controlled to ensure
efficient operation, particularly through the bottlenecks at Minories
Junction,

If a DLR train ends up at Minories Junction, the bottleneck is
probably the least of its problems...

ITYM Royal Mint Street Junction.

I still find it quite an accomplishment to see Canning Town and
Stratford bound trains pull in alongside each other simultaneously at
Poplar, thus allowing cross-platform interchange. The same applies in
the other direction with trains bound for Canary Wharf and Bank/Tower
Gateway.

This ability for the DLR to run like clockwork would all fall apart if
there was any on-street running.
