CQL comes from a standard (some kind of library standard I think?). It is used by the open geospatial consortium catalog specification which is why we bothered with it. The standard is strict and kind of matches up with the Filter objects we use for GeoTools. The idea of having a property in each filter is part of that filter standard.
There is an ECQL (ie extended!) which should let you make invalid queries such as 1=1 Give it a go; it is what I use for uDig - and it has some other extensions that make creating "feature id" filters easier.
