I'm in this same situation as well. I checked out the source, and it
appears to be designed this way.
This information is coming from running "apt-cache policy" and is parsed
as explained by this comments:
# If the user has multiple releases we should
# only return the 'newest'.
# Unstable is always the 'newest'
It's my opinion that this behavior is "wrong," and if it's going to
continue to use apt-cache policy (instead of /etc/debian_version or
something), it should be based off the highest priority [for c=main,
which is already enforced]. I think maybe it should also enforce
label=Debian, so we're not parsing the Debian-Security repositories, too.
I've attached a patch that addresses these issues, and changes the
behavior how I've noted I feel it "should" behave.
