New description:

 My use case is: at the startup of my application, I want to show all
 features. Then later on users can control the visibility of features by
 using checkboxes in a legend, so I will use setFilter then. However, now I
 have to instantiate my Filter strategy with something like (a filter that
 matches everything):

 {{{
     new OpenLayers.Strategy.Filter({
         filter: new OpenLayers.Filter.Comparison({type:
 OpenLayers.Filter.Comparison.LIKE, property: 'categorie', value: ''})
     })
 }}}

 How about allowing instantiating the strategy with no filter?
