Only those who use winner, apparently.  This incident tells us nothing
about those who don't use winner, right?

Up until now, the rules for pre-loading package X were that either
(a) some preloaded package requires X, or (b) X will be auto-loaded at
the beginning of every session by some very frequent operation, like
visiting the first file or creating a window or a frame.

Since winner is itself an optional package that not everyone uses
(e.g., I don't), this case doesn't seem to qualify, IMO.
