Yes, and I believe that's what we should really fix, and currently being
fixed by the rumpdisk translator.

Departing from the current way d-i works is asking for maintenance

Another way would be to just include all required d-i packages in the
d-i initrd, making it bigger. The rest can be fetched from the internet.

That is *exactly* what the initrd already is.
The fact that the installer loads .udebs on demand is just a way to
support lots of situations without loading everything altogether in

What do you mean by "break"?

When the filesystem is not properly shut down, one has to run e2fsck,

Returning to grub is a requirement when it is the root filesystem that
got mangled by fsck: the existing ext2fs has to reload all of the data
since it was mangled. Just rebooting is way simpler than trying to track
everything that should getting re-read.
