packages removed by Release Manager just reveal older versions

[Dan Jacobson <jidanni@jidanni.org>]

Regarding packages removed by Debian's Release Manager, due to
Release Criticial bugs, but say, still looking great here:
$ apt-cache policy deity
deity:
  Installed: (none)
  Candidate: 0.8.0.6
  Version Table:
     0.8.0.6 0
        500 cdrom://[Debian GNU/Linux SID _Sid_...

there seems no mechanism at present to warn the user that he shouldn't
install it, even if he has done apt-get update from the mirrors.  In
bug 202919 you will see I was just lucky something stopped
installation.

I guess I'm hoping for a warning that a package is 'out of fashion'
when I try to apt-get install it.
