If an application wants to rely on "==" then "most of the time"
just isn't good enough. The filter needs to know definitively.
If the concern is only memory efficiency, then I tend to agree
that there may well be more important things to worry about.
But maybe not; so the filter can benefit from knowing if the
data it gets is already interned.
