I can't think of anything currently available that's as elegant as the above -- could you add a suggestion for this in JIRA?

You could try something like this to pause the animation:

SequentialAnimation {
    id: group
    NumberAnimation { to: 200 }
    ScriptAction { script: if (!myComponent.isReady) group.pause() }
    NumberAnimation { to: 400 }
}

and then elsewhere call group.resume() whenever the condition is met.
