I take your "No" and re-raise it to "No, yes, but twice".
apt-cdrom is run twice, first as I described it. Feel free to check it
yourself, the first package installed (aka the first entry in
/var/log/apt/history.log) is 'locales' because everything not part of the
bootstrap is installed with apt-get which uses as source the cdrom
(what else, as mirrors aren't configured yet).
After some more packages are installed the installation reaches the apt-
setup stage in which a mirror will be chosen - but as its first task it
runs apt-cdrom again as you said it - in the locale chosen and installed
earlier. This makes this problem actually solvable, at least for installers
with that behavior …

As said, apt-cdrom never did and nobody changed it until now - likely also
because nobody of the few people who take care of APT use apt-cdrom on
a daily basis currently - or at least in my case at all.
(which explains a few more needed bugfixes in upcoming 0.9.7.5 …)
I wonder how many people actually depend on that behavior (meaning especially
other distro-installers and multi-language systems), but ignoring my fear to
be once again be flamed to death for an "easy and only logical" behavior
change I just changed apt-cdrom to drop all not configured Translation-*
files from the copy list.
Meaning that on the first run above you will get only Translation-en, while
you get Translation-en and Translation-$LANG (and possibly some more friends
defined by the various environment variables and configs) in the second.
Installers allowing to create multiple users while installing (with different
$LANG) need to re-run apt-cdrom in all of these $LANGs to get the optimal
behavior.
I tried it with a modified multi-arch beta1 cd [0], so at least for debian
it seems to work, but I only run it until a mirror is chosen for the lack
of network, so more testers are welcomed of course …
(You find it only the bzr branch for now, as we haven't made our minds
yet how to solve #686346 without too much work and breakage risk -
life would be so easy if dpkg and APT^Wmyself would agree just once …)
If someone feels the urge to kill me for this change now: Add
APT::CDROM::DropTranslation false;
to your configuration file/commandline invocation and you are back
to your "normal" and beloved previous behavior.
