I agree it would be nice to have seen, or at least heard, where some of the more impactful of the previous characters are. If they were going to end Dragon Age Keep, they could have given us more customizable choices when setting up the initial game parameters for Veilguard. Did the Hero of Fereldan survive? How about Hawke? Where are they now if they did? Surely Varric would know about Hawke, at least, and the Grey Wardens must know something about the Hero of Fereldan's fate. How about Divine Victoria? Which of the three is she in a given playthrough? Given the different visions each of the three candidates had for the Chantry and Mage Circles, it could have some impact on the game world, at least in terms of the news you get from the South. And yes, the connection between Sandal's abilities and the Titan blood storyline would have added something too.
