```
control.Event.may_have_added_a_pane(self) -> bool
```

Report whether a pane may have appeared since the last look.

tmux publishes no notification for a pane being created, so this is a
conservative union of the events that can accompany one. A caller that
narrowed with [`ControlSender::watch_only`] must repeat it when this
answers `true`.
