QMap explicitly sorts its entries by key value. For an ordered container it's (often?) useful to access the first or last entry, for instance to quickly compute the next key of the mapping. The first entry is easily accessible by the STL begin() method, but for accessing the last entry pretty ugly iterator arithmetics must be applied: *(end() - 1). With their first() and last() accessors the container classes QList and QVector provide a much nicer method of accessing extrema, so for consistency this syntactical sugar also should be applied to QMap.
