I don't understand your point. It's a computer program - it's going
to do *something* under these circumstances. The people who specify
the program behavior must decide what it is going to do. The decision
may be difficult, but it must be made nevertheless.

It may be hard, but that does not absolve the designer from
deciding what it should do. If you choose not to decide, you
still have made a choice.
