Oh it works. This is why I ask these questions -- new perspectives!

There are over 20 million records in a self-referential database table, where
one record may point to another record as a descendant.
Because of a bug in application code, there was no limit on recursion. The max
was supposed to be 4. A few outlier records have between 5 and 5000
descendants
