My reasoning was |MarkRemovePredicate| is general term and when we use this for
using other purpose other than custom dictionary update.
However, it is too nervous. When we'll use |MarkerRemoverPredicate| with
thousands of words, we'll change it to |HashSet| or another for efficient look
up data structure.
