Debian templates cache downloaded packages

[unman]

Qubes OS version
R4.0

Affected component(s) or functionality
Debian templates

Brief summary
Installed packages are cached in /var/cache/apt

To Reproduce
Steps to reproduce the behavior:
_1. Install packages or use qubes-updater
2. ls /var/cache/apt/archives

Expected behavior
Packages will not be retained in cache

Actual behavior
Packages are retained in cache.

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
We clean cache after installation.

Although this is standard Debian behavour, in Qubes context, I'm not sure it makes sense to retain packages in cache for every template.
That said, /var/cache/apt/archives is important and shouldnt be removed

Solutions you've tried
apt-get clean is standard route.
Setting APT::Keep-Downloaded-Packages "0"

Relevant documentation you've consulted
A list of links to the Qubes documentation (or other relevant software documentation) pages you have already consulted.

Related, non-duplicate issues
A list of links to other bug reports, feature requests, or tasks in the qubes-issues tracker (or "none" if you didn't find any). Do not describe any other unreported bugs, features, or tasks here.

Since this has the 4.0 milestone, the fix is pending backport to 4.0, right?

If it's not there, yes.

I didn't think it would already be there when there are no qubesbot comments on this issue stating so.
