Frameist, it is hard when children do not receive what they need educationally or otherwise. While there might be truth to the thought that you could have done better by taking your own initiative, I hope you remember that you were a child then, and many (if not all) of these decisions were not within your control, so you cannot own the responsibility for those decisions. What I particularly appreciate about your thoughtful posts here is that you are trying to transform the hard lessons learned from your own experience into better proactive decision-making on behalf of the potential future children to which you have alluded (as well as other people's children that you might encounter along the way).
And on the original topic: I too strongly prefer that all options are considered, including but not restricted to grade acceleration. "No" change is still a choice, and not always the do-no-harm one people may think it is. One should also consider that the complications that institutions often claim are reasons not to accelerate are sometimes actually symptoms of the problems that might be solved by acceleration.
