In general what I learned: You find an obscure, not useful, not used feature in the code base that complexities everything.

option 1) Ask the list.
� � � � Result: 5 people will suddenly realize that they can not live without that strange feature they never heard about before.

option 2) Just kill it.
� � � � Result: the World is a happier place.

;-)

But seriously I used that Strategy 2) a lot in the past :-)
