I tend to think bigger picture and don't resort to simplifications just
because they are simpler or faster.

Reasons that come immediately to my mind to only use an svn export (from
a specific 'tag':

- stability - you can always see what was packaged by doing a checkout
in another directory or on another computer.

- repeatability - you will always get the same files regardless of
where, how you package them.

- durability - one of the reasons you chose a version control system in
the first place... that if the system that you built it on or saved it
on isn't available, you still can get the files that comprised the
package.

- identification - easy enough to tag and identify which version but if
you have some 'build machine with a recent working copy of the branch',
that machine is going to change if not within minutes, certainly in some
days.

There's a reason that management systems and practices are developed and
rarely do they focus on simpler or faster.
