The prime use case is in isearch. At the moment isearch doesn't work
well when Follow Mode is active (try it!).
My first attempt at amending isearch for this involved manipulating
Follow Mode's list of windows directly inside isearch.el. The result
was too close a coupling between isearch and Follow Mode, and was also
rather ragged. Stefan rejected this patch, asking for a more abstract
solution.
What I am proposing now is a solution where any library which needs to
manipulate things like window positions will be trivially upgradable to
working with Follow Mode, merely by replacing `window-start' by
`window*-start', etc.
The fact that the "group" of windows is represented by a list is an
implementation detail to be encapsulated within follow.el. In the
(fairly distant) future, this might perhaps be superseded by code in
redisplay. Perhaps.
