Random testing.  E.g., someone reports a certain behavior with a
non-default setting, or I learn about a new option and want to try it
for a while, then revert back if I don't like it.  Also, some unusual
situations that I don't expect to repeat too often, like a file with
unusually long lines that defeats line-number-mode.
