Yes, just an oversight.

+Using these new binary seeds the ``missing'' Binutils, GCC, and the GNU
+C Library are built from source.  From here on the more traditional
+bootstrap process resumes.  This approach has reduced the bootstrap
+binaries in size to about 145MB in Guix v1.1.
+
+The next step that Guix has taken is to replace the shell and all its
+utilities with implementations in Guile Scheme, the @emph{Scheme-only
+bootstrap}.  Gash (@pxref{Gash,,, gash, The Gash manual}) is a
+POSIX-compatible shell that replaces Bash, and it comes with Gash Utils
+which has minimalist replacements for Awk, the GNU Core Utilities, Grep,
+Gzip, Sed, and Tar.  The rest of the bootstrap binary seeds that were
+removed are now built from source.
+
+Building the GNU System from source is currently only possibly by adding
+some historical GNU packages as intermediate steps@footnote{Packages
+such as @code{gcc-2.95.3}, @code{binutils-2.14}, @code{glibc-2.2.5},
+@code{gzip-1.2.4}, @code{tar-1.22}, and some others.  For details, see
+@file{gnu/packages/commencement.scm}.}.  As Gash and Gash Utils mature,
+and GNU packages become more bootstrappable again (e.g., new releases of
+GNU Sed will also ship as gzipped tarballs again, as alternative to the
+non-bootstrappable @code{xz}-compression), this set of added packages
+can hopefully be reduced again.
+
+The graph below shows the resulting dependency graph for
+@code{gcc-core-mesboot0}, the bootstrap compiler used for the
+traditional bootstrap of the rest of the Guix System.

+
+The only significant binary bootstrap seeds that remain@footnote{
+Ignoring the 68KB @code{mescc-tools}; that will be removed later,
+together with @code{mes}.} are a Scheme intepreter and a Scheme
+compiler: GNU Mes and GNU Guile.
+
+This further reduction has brought down the size of the binary seed to
+about 60MB for @code{i686-linux} and @code{x86_64-linux}.
+
+Work is ongoing to remove all binary blobs from our free software
+bootstrap stack, working towards a Full Source Bootstrap.  Also ongoing
+is work to bring these bootstraps to the @code{arm-linux} and
+@code{aarch64-linux} architectures and to the Hurd.
