The limit is there to avoid infinite loops in tenant-utils in case of
cyclic parent pointing. There is no way I;m aware of to create such loops but
bugs may prove me wrong:)
As I set a limit in the loops themselves, I wanted to keep the code
coherent and block the option to create deeper hierarchy.
