Well, the question is what "derived class" means, but I'd tend to think
it means something that has an associated composite type; which indexes
do not. So maybe instead of "has (or has had) derived classes", we could
write "has (or has had) child tables or indexes"? I'm not wedded to
particular wording for this, but I think what's there now is a bit
misleading.

Good point, that column's description is obsolete as well.
