Or perhaps I should say 'what was the motivation for building it'?

I only ask because London Bridge is a mere ten minute stroll from
Cannon Street. Presumably Cannon Street trains have always passed
through London Bridge (apart from those heading towards Charing
Cross). So why go to the expense of building viaducts from the Borough
Market junction, bridging the river, and building a terminus station
at Cannon Street when it's virtually within spitting distance of a
much more significant station at London Bridge? Was it perhaps
intended to extend the line further north at some point?

London Bridge is only significant because so many trains go there or
through there. Nearly everyone arriving there by train immediately
goes somewhere else, by another train, by Underground or by bus.

Cannon Street is in the City, where many people actually need to go.
It also has room for trains to turn round, which three platforms at
London Bridge would not be adequate for.

You might as well suggest that all trains terminate at Clapham
Junction instead of going to Victoria or Waterloo, since it's a more
significant station than either by the same definition.
