Lots of people are expecting 'Saved Tabs' to work like bookmarks where they don't have to worry about loosing them on restart. If users are taking the time and effort to create/save new tabs then they better stick.
We are doing the correct thing by blowing away a users tab groups if they are not electing to use session restore. We should, however, be doing a better job of educating users about session restore, specifically in Panorama. One bug to address this issue is bug 589665
