I see what was unclear in my example. builder.1, builder.2, builder.3 are
steps 1, 2, 3 of one builder

So you have three steps of one pure local builder (it doesn't execute any
remote code). Having a dedicated "local" buildslave for such builders which
doesn't execute any code sounds like overkill. (In fact, i agree, it isn't
an overkill from the POV of system resources, it's more like
must-be-generalized of the BuildBot concept).
