I think the possibility to fill up /var makes it a poor choice. Putting each user's mail in their home directory is, imo, a more sensible choice. Now, there are a dozen legacy reasons why we may not be able to do this by default, but we should encourage anybody changing the defaults to avoid /var/mail. Even traditional mail only uses /var as a queue, and then stores messages in ~/mbox. In short, we can't simply drop /var/mail support, but if through inaction we can discourage its use, then I vote for inaction.
