You have to be a little careful there. As I understand it that protection 
relies on a self-consistent package database. You don't notice this if you 
use portupgrade because it needs the same self consistency to function and 
massages the dependencies (or refuses to do anything until you fix them 
manually)

Whilst portmanager can leave behind these dependency mismatches (when you 
don't fully update your ports), it's own leaf-deletion option doesn't seem to 
be thrown by them.
