Yeah but debian-installer doesn't have bzip2 and xz in the host so it's
not really useful... you saw the recent bugs when libacl used bz2

This is mostly moot, it's 10Mb with the default compression level that we
plan to use.

This is true but it's relatively small in size.

That said if you want to avoid it, what are the base packages where
it must absolutely be avoided?

All essential + their (transitive) dependencies?

I mean at some point dpkg and their dependencies have been unpacked
and debootstrap can/could switch to the chrooted dpkg instead of using
tar.xz + ar from the host.
