IMHO some of these should probably have never existed in the first 
place: ie 
since they are near impossible to ever migrate away from once created (a 
"JSON-based grammar for selecting hosts", like woah). So if someone is 
going to do a comparison/experiment I'd hope that they can overlook some 
of the filters that should likely never have been created in the first 
place ;)
