I'm not an expert in this matter, but it seems that the aspect of the chart that folks are questioning is the timeline. Could it be as easy as removing that aspect to dissuade the perception of a pseudo-commitment when presenting the roadmap?

That could be a way to go. Another option to represent time in a less fixed manner is to use a now-next-later roadmap schema. It's more to the point of what's important vs. time as a measurement.
