Ah, and now I see that it's too cryptic/terse too.  How about

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.

I have to ask since we're talking about bootstrapability; is it actually
not bootstrappable or is it just harder/more complex? (The question is
more about the wording than about the logistics of it.)

Hello,

I have a couple more nits.

OOC, why are you using single quotes here? You used double quotes
everywhere else. I assume this is an omission.

gzip is about 7000 LOC of simple C, can be compiled with tinycc (and
probably mescc), and we have gzip in Gash.  That Scheme code is not
trivial but with not too much work we can have Mes run that code.  It's
also conceivable to have an M2-Planet port of gzip.

xz is about 25,000 LOC of C and I only managed to build it after having
a full fledged gcc-4.6, gcc-2.95 or tinycc did not work for me.

So, if SED only ships xz-compressed tarballs, that makes
creating/maintaining the GNU bootstrap story more difficult.

Greetings,
Janneke
