I wonder what the purpose was... the original poster never replied.
Just on topic: I have generally made allowances in some modules (especially payment processing modules) which bypass certain actions and continue processing a request which would otherwise fail.
The reasoning is to allow administrators and programmers to run system checks or track possible issues without extensive roll back actions.
The clients are made aware of such modules and the option to remove this functionality always exists.
Classified as a "backdoor" guys?
