For a recent checkout of Guix from master, I saw:

while a recent pull of wip-go-updates showed this:

That looks very respectable to me for such a comprehensive change, but
I can ultimately not assess whether it's a good ratio.

It looks like perhaps seven items are failing due to our changes (on
x86_64, and out of about six hundred) but I do not know how important
they are for average Guix users.

Kind regards
