Bug#1059629: apt: doing something like 'apt -t rc-buggy --upgradable list'

[Patrice Duroux <patrice.duroux@gmail.com>]

Package: apt
Version: 2.7.7
Severity: wishlist

Dear Maintainer,

I do not know if there is a simple way to get such a list with also another
command like dpkg-query or apt-get.
I known that 'apt -a list' may be a part of the answer as it gives all
available versions in the current apt setting,
for instance regarding my system:

...
gir1.2-webkit2-4.0/experimental 2.43.3-1 amd64
gir1.2-webkit2-4.0/unstable 2.42.4-1 amd64
gir1.2-webkit2-4.0/oldstable-security 2.42.4-1~deb11u1 amd64
gir1.2-webkit2-4.0/oldstable 2.40.5-1~deb11u1 amd64
gir1.2-webkit2-4.0/bullseye-backports 2.34.2-1~bpo11+1 amd64
...


But using 'apt -a --upgradable list' gives the same result as 'apt --upgradable
list'.

Regards,
Patrice
