I don't think it is still "required" but it used to be that upgrading versions mandated full-scan statistics updates on all statistics in every database migrated.
Not at all required, but not at all a bad idea. You will get a stats update on restored statistics from an old version now. However, that means waiting for each one to come up. I'm not crazy about that approach. I like yours better.
