Imapflags "hasflag" test interaction with relational draft

Ken Murchison has asked me how "hasflag" test interacts with relational 
extension.
hasflag :count will count the number of different flags in a variable.
So
hasflag :count "ge" "MyVariable" "5"

returns true if the number of different flags in MyVariable is >= "5". 
However note that the default comparator is i;ascii-casemap and not 
i;ascii-numeric. I.e. hasflag test doesn't have the comparator 
parameter. Does anybody see any value in adding the comparator parameter 
to hasflag test?
