Unless there is a information source I am not aware of, you won't find this information readily available and you may need to browse through the RMs.
A slight help might be looking at the timeline of introduction - as soon as you find a family without this feature, most likely older families won't have it either. In other words, newer families tend to use the newest verison of the IPs used in configuring them. This is onlya coarse guideline; there are exceptions.
