Let me elaborate a little bit.
The reason the packages you'd expect to be marked "auto" are not marked as
such is because debootstrap (and tasksel as well for the 'standard' task)
simply install *all* packages that have a certain priority. Because the
packages are all installed by name, they will not be marked "auto".
The reason all these packages are the same priority is because that's a
current Debian Policy requirement : packages cannot depend on other
packages with a lower priority.
The simplest way to "fix" the issue  would be if libraries etc. would be
allowed to have a lower priority (e.g. optional). That would mean that
they'd no longer get installed by name, but pulled in as dependencies and
thus marked "auto".
There are some arguments why the policy could be changed, but that would
require a serious discussion within Debian.
The main argument would be that the policy was probably originally created
*because* tools like debootstrap and debian-cd did not support dependency
handling. No that they do, the policy could be changed. But there may be
other reasons I'm not aware of!
I've considered starting this discussion a few times, but haven't yet done
 It's also quite probably the *only* correct way to fix the issue...
