You seem to be misunderstanding some things fundamentally here.
.udebs and .debs are *completely* separate and saying that D-I "needs both"
makes absolutely no sense at all.
.udebs are the building blocks of the installer itself and are *never*
installed in the target system.
.debs are the building blocks of an installed system and are *never*
installed in the Debian Installer environment [1]; the only way D-I "uses"
.debs is to install them into the /target chroot for the new installed
system; D-I itself *does not* "need" .debs.
.udebs and .debs can and will NEVER depend on eachother.
When D-I is running you need to always distinguish between these two
things:
- the D-I environment (everything except the /target directory)
- the target system environment (everything under /target)
And possibly as a subcategory:
- the installation media (things mounted under /cdrom and /hd-media);
note that /cdrom can also be mounted under /target during the install

This is very simply the definition of what the base system is. You should
study 'debootstrap'. Packages are included in the base system on the bases
of their Priority field (important or higher).

Packages that are apt-installed are installed by D-I for the target systems
because D-I "detects" that they are needed in addition to the base system,
either the result of hardware detection, or because of choices made by the
user during the installation process.

No, it does NOT "depend" on them. That is a completely wrong way of
thinking about it!

You should really try to understand basic Debian package management
concepts better before trying to work with D-I on this level. I'm afraid
that this mailing list is not really the place to teach you about that.

something that should really be fixed.
