In that world, I think people wouldn’t say “we have AGI”, right? Since it would be obvious to them that most of what humans do (what they do at that time, which is what they know about) is not yet doable by AI.
Your preferred definition would leave the term AGI open to a scenario where 50% of current tasks get automated gradually using technology similar to current technology (i.e., normal economic growth). It wouldn’t feel like “AGI arrived”, it would feel like “people gradually built more and more software over 50 years that could do more and more stuff”.
