I may want to prepend a log line with not just a timestamp
but also other information such as user, group, hostname etc.
This change may be small but it does not belong in date(1).
Just as I wouldn't want to extend hostname(1) to be a filter.
It makes more sense to extend logger(1), not date(1).

Don't mess with my date:-)
