featurectomy

featurectomy /fee`ch*r-ek't*-mee/ n.  The act of removing
   a feature from a program.  Featurectomies come in two flavors, the
   `righteous' and the `reluctant'.  Righteous featurectomies are
   performed because the remover believes the program would be more
   elegant without the feature, or there is already an equivalent and
   better way to achieve the same end.  (Doing so is not quite the
   same thing as removing a {misfeature}.)  Reluctant
   featurectomies are performed to satisfy some external constraint
   such as code size or execution speed.
