Yay!

> +@subsubheading Guix Build Coordinator
> +The @uref{https://git.cbaines.net/guix/build-coordinator/,Guix Build
> +Coordinator} aids in building derivations.  The Guix Daemon is still
                     ^
Maybe something like: “in distributing derivation builds among machines
running an @dfn{agent}”.

Also, s/Guix Daemon/build daemon/ or similar.

(In general I’m in favor of avoiding “brands” in documentation and
concept names.)

Maybe add a “@quotation Note” stating that it’s work in progress and
subject to change.

Perhaps there should eventually be a ‘guix-build-coordinator’ command in
the package itself?

Otherwise LGTM, thanks!

One thing we discussed on IRC is the name and ways to set up one’s
monitor so that
guix-build-coordinator-configuration-client-communication-uri-string
fits on one line.  :-)

An idea that came to mind was “(Guix) dispatch(er)”, which is
synonymous.  You could use the (guix dispatch …) name space.
Food for thought!  (No rush, of course!)
