Right that sounds like a bug.

Good solution :)

True.

I think that the real solution is to see if there is a proxy in
use on the host, and if so create the identical proxy in the new
guest.
That seems like it would satisfy your goal whilst still being
understandable. (Alternatively testing for "${http_proxy}" might
work.)
So I'd suggest that the setup apt script was prefixed with this:
--
#
# Process any of the present apt-conf setup lines.
#
for i in /etc/apt/apt.conf /etc/apt/apt.conf.d/* ; do
#
# If the file exists. (Need this in case the literal glob fails.)
#
if [ -e $i ] ; then
#
# Save the matching line(s) to the proxy guess file.
#
grep -i HTTP::Proxy $i >> ${prefix}/etc/apt/apt.conf.d/proxy-guess
fi
done
--
Does that seem reasonable? And if so would you mind testing it?
