This is a somewhat obviously useful direction to go in, but not necessarily for
ordering problems, as Nicholas quite rightly points out. The current
implementation is careful to leave this option open, as is the current zones
implementation.

There's no good answer to that. What does "started completely" even mean? It
entirely depends on what you're asking and why. In such circumstances, a
feature-based test (even if it must be a polling loop) is still the best
option.
