Sure, while editing it's useful to be able to tell the difference
between "you used a node which has since been deleted" (and thus could
be undeleted) and "you're using something that never existed (and thus
reveals a bug).

I don't think performance-wise it would make a difference on a good
database, but I'm unsure about mysql.
