But my understanding was that this part of the discussion was focused on
the distinction between "may run redisplay/jit-lock during the execution
of the command itself" vs "only runs jit-lock/redisplay once the command
itself is over".

AFAIK `scroll-conservatively` only affects the redisplay so it can't
affect the above distinction.
