No, it doesn't need to be preserved (as everything in /var/cache),
but depending on your usage pattern it can save you bandwidth or
can come in handy if you want to downgrade or to move the files
to another computer without a network connection…
You can use 'apt-get clean' or 'apt-get autoclean' to clean up
this directory. For the difference please have a look at the manpage.
P.S.: These kind of questions are better asked on the debian-users
mailinglist (or their localized offsprings), ask.debian.net or alike
as this is more a develer-discussion than user-support list.
