That would break their system as daemons have no way to notify the user
something is wrong.  Instead, I bet that you read popcon's vote<installed
that way -- which at least in this case nearly always means the user has the
filesystem mounted noatime.

Which is a damn reasonable thing to do, as it prevents every write from
having its metadata cost doubled.  Current Debian's default, relatime,
sacrifices performance and causes unnecessary spin-ups, with the stated
explanation being certain uses of mbox, a long-obsolete format that might be
adequate at most for rare mail from daemons but not actual mail from live
people[1].  And even that is fixable by making mail readers manually set the
access time.

[1]. How many non-technical folks you know who do not add fat attachments to
a majority of mails?
