gentoo-sources is not part of the guaranteed package set for the
binhost. Any package *may* end up built on the binhost, either as a
dependency for another package that stops being a dependency because the
other package has changed, or due to the fact that we run a few
different build configurations, including choosing a couple packages by
lottery each day. Those may be available only for an older version in
the ::gentoo tree if they don't get lucky a second time.

It is only the default when using --getbinpkg, not when you are instead
using --getbinpkgonly.
