Ah, maybe because you were too fast: it depends on
a18d02def9862dfb9b7a5e3d5aa3b541b066d198, which I pushed yesterday.

The idea was to expose only ‘%default-channels’, which leaves room for
the possibility of having multiple channels by default.  I’d rather
avoid exposing the individual bits as that’s a bit of an additional
committment.

But note that the introduction of the “official” guix channel is
automatically added anyway (commit
c3f6f564e909ebefe752d24b325871a4e3a02d40).

Thanks for your feedback!
