No, it's smart. To allow save importing would have meant a lot of work creating a save importing system. Odds are that the way the data is stored on the Keep is totally different from how it's saved in a save file. So they would have to create an entire new parsing system to extract the information from save files. That's not a non-trivial task.
In addition, current gen was clearly a higher priority than last gen, so why waste time, money and resources on a system that only a small fraction of the player base will utilize?
It's also more useful to the player, because they can set their worldstate as they wish, instead of having to play through the entire series all over again.
The Keep is the future. Better that players embrace it now.
