misfeature
     
        /mis-fee'chr/ or /mis'fee"chr/ A feature that eventually
        causes lossage, possibly because it is not adequate for a new
        situation that has evolved.  Since it results from a
        deliberate and properly implemented feature, a misfeature is
        not a bug.  Nor is it a simple unforeseen side effect; the
        term implies that the feature in question was carefully
        planned, but its long-term consequences were not accurately or
        adequately predicted (which is quite different from not having
        thought ahead at all).  A misfeature can be a particularly
        stubborn problem to resolve, because fixing it usually
        involves a substantial philosophical change to the structure
        of the system involved.
     
        Many misfeatures (especially in user-interface design) arise
        because the designers/implementors mistake their personal
        tastes for laws of nature.  Often a former feature becomes a
        misfeature because trade-offs were made whose parameters
        subsequently change (possibly only in the judgment of the
        implementors).  "Well, yeah, it is kind of a misfeature that
        file names are limited to six characters, but the original
        implementors wanted to save directory space and we"re stuck
        with it for now."
