It _does_ happen. In the current flow grub-installer is the first component to run os-prober which loads some new udebs (ntfs/qnx4-modules).
Another case where the installation CD must be loaded is when the 50mirror generator is run because it checks files in /cdrom/.disk.

I do store the ID of the installation CD in the 41cdset generator. That generator, pkgsel and apt-install all make sure that that original CD is reloaded and mounted before they exit (using the new script load-install-cd), so any anna-install call should never find itself with the wrong CD in the drive.
Storing the ID could maybe be done in cdrom-retriever. OTOH, I currently use 'apt-cdrom ident' to determine the ID and that is not available at that early stage.
Of course, if we do want to implement a check in anna/udpkg that the correct CD is available, this will have to be rethought.
