No, APT has never copied anything except the index files when used with
file URIs. With APTv3 you can ask it to copy by using a 'copy' URI, the
choice is yours.

APT v3 in CVS supports -o APT::Immediate-Configure=false which disables
this behvior, only pre-depends will cause it to run a seperate dpkg which
the other methods do as well.

I'd be interested to know how any other method handles this, how do you
inform dselect what packages are in your local mirror so you can select
them? If you have an incomplete mirror with a matching package file that
has extra entries then APT v3 will be perfectly happy, if not a bit
verbose as it has an automatic source fail-over mode, files that are
missing or outdated will be fetched from a remote site if you enable that.
