The idea is to catch a few things in our test beyond needs of apps known to 
us. Some of my tests test things even though I had no application that really 
needed it. So I prefer to document things I come accross, even if I can't see 
an immediate use, and will most likely never have a use. You never know what 
the future brings.

I do not claim that I have a scheme when writing tests for unused functions or 
not doing so, it mainly depends on wether I'm in the moot of writing a 
test :-)
