Comment (by joemcgill):

 I agree that a pre_ filter name would be better here, since we're not
 filtering the return value from the DB, good suggestion @emrikol.

 @oglekler there isn't a specific performance impact to adding the filter
 here, but it does create an opportunity for sites to potentially avoid an
 expensive DB query, which is why it makes sense as a performance
 enhancement.
