Because you may regret it later, unqualified addresses are implicitly
qualified with $myorigin, which may or may not stay local in the future.
Are you aliasing the user whose email address is "u...@example.com",
and whose mailbox may be subject to further independent rewriting/routing?
l...@example.net u...@example.com, ...
Or are you aliasing the local mailbox of the Unix login account "user"?
l...@example.net u...@localhost, ...
Or are you aliasing "user" in the default mail domain of the system
($myorigin), who would receive unqualified email sent by e.g. cron?
l...@example.net user, ...
For lists, the first use-case is the most common. The 3rd use-case
leads to surprises when $myorigin is changed to be non-local, but
local delivery was intended (a mis-configured case 2).
