It makes me think of another point. There are some detectors that do exactly 
the same detection procedure for all supported types. For example - oox, xml, 
and now the new storage one. If such detector didn't detect anything useful 
once, we can be sure that it won't detect anything also in the next runs. So 
it doesn't make sense to run it again and again.

Maybe we can store a list of such detectors in some config file, and add a 
corresponding check to the detection loop. This also would be a bit cleaner 
solution for fdo#46310. What is the best place to store such list?
