To understand why QUIET is not the default, you have to think about the
poor subscribers who do want to be informed about unexpected changes to
their subscription (when they did not explicitly ask the list owner to
make the change). This is why QUIET is not the default, in fact QUIET is
supposed to be used:
- For "mass change" operations, which are better advertized with a
posting to the list.
- For accounts which have been deleted and would get you another piece of
junk mail if you didn't use QUIET.
